Mis-fire
 

Now the Bear throws up another problem. Under power she hesitates, like a mis-fire but only on the go. Stationary she revs ok. I’m assuming it’s a coil pack problem.

A lesson learnt over years- any mis fire and the first thing to consider is a faulty coil pack and or leads - exacerbated in colder weather. Dont forget any sustained driving with a repeating misfire can knacker your Cat as i know to my cost.:icon_redface:

Your cars only do this to enhance your learning!

Fit a set of MSD's, it will be the best money you have spent. It will start easier hot or cold and you will feel the difference when you drive.

Best place to buy these MSD’s?

Rock auto for all Crown Victoria stuff Bob :xmas-smiley-008:

Please enlighten me MSD,s ??

You wont get a set of MSD's from Rock Auto. These are high powered better quality ignition coils.


I usually have a look on US Ebay and Amazon but if you put that part number in Google you should have some options. Probably going to be £250 ish by the time you have paid the shipping and import duty.



Just looked and there are a set here https://www.amazon.co.uk/MSD-82428-B...%2C1135&sr=8-1

Many thanks but I refuse to deal with Amazon as they allowed my credit card to be cloned twice. But I will look on the US eBay site.

Bob,
Try eBay .com (USA) . I got my spare set from there , loads of options inc. MSD

Even eBay UK have a lot..

European distributer, Gooze in Holland. Very fast service.

I have heard about that before, the way to get around it is use an American Express card, American Express are on your side what ever the problem unlike a lot of Credit cards. Yes there is an annual fee but get one with rewards and you more than get the fee cost back. My card got cloned while on Holiday a couple of years ago, they cancelled it, refunded the amount that had been scammed immediatly and the best bit had a courier sent to me with a new card the following day at my holiday address.

They seem to sell many parts. Which ones do you mean or do you mean everything they sell.--That could be expensive as the OP might have any of those ignition parts faulty.---:shocked::shocked::shocked:

There's a Set of used Std ones on Fleabay BOB ? , linky

I’ve bid on them. Cheers Chris.

Seven available but selling singly not as a "set".

Ah! I didn’t read that bit correctly. Hopefully I’ll get outbid. Started to save up for a brand new red topped ones. Might have to sign up for a paper round. “Anyone seen my cycle clips”.

If one has failed, Peter, the eBay seller, has probably decide that replacing all 8 would be sensible, rather than being let down again, hence the 7 left over. Probably selling those old ones now to "subsidise" his MSD purchase !

Never regretted buying my MSD's. Now I've still got 7 original old MGR ones over too, but although all were "working" when I swapped them out, I would feel guilty about actually asking money for them; 2nd hand COP's? Emergency use only, surely.

You have to scroll down to the item description:

Used but in good working order

7 available (replaced all 8 but only one that had failed.
This auction if for 1 item

One day you may reach my age, then you’ll understand.

Just having a senior moment.

Sorry but not really been in the mood to look into it today, but I will tomorrow. Many thanks for the advice.

Well I bid on the said single item and won it for £8 plus p&p. However today I have received a message from eBay telling me that my order has been cancelled and my money refunded.

The seller sent me two messages, bot the same. He has informed me that he is having issues with the advert on Gumtree.
More than likely he was hoping for more money to be raised on the item.

If you want a single one my local Motor Factor got one for me. There are also some single new ones listed on Ebay.

[QUOTE=Arctic;2913999]Well I shall not be bidding.

This is the message I got from eBay

Hi Bob,
We are sorry to let you know that peterone1 cancelled your order and mentioned the cancelled reason as 'I'm out of stock or the item is damaged.'
You received a refund back to your original payment method, you don't need to do anything else. It may take 3 to 5 working days for the refund to be completed.

Hi, similar to my experience a while ago,ordered a hallway runner to put under one of my motorbikes,came back with that message,so ordered another through a different supplier and got the same message.When I asked for a refund e bay then added that I (the buyer)had cancelled the order!
Regards Ryszard,and have a safe new year.😷

The Bear was very reluctant to start this morning. I have been out starting her up every couple of days. I let her warm up before pulling away. Managed to get her to the garage, although she mis-fired all the way. (It’s less than a mile to the garage).

Bite the bullet and order a set of MSD's from Gooze.
Suspect your problem will be solved, and the car will run a bunch better than before the problem set in too.

How many coil packs do you need? I have two complete sets doing nothing that I removed from my V8's. Nothing wrong with them I just upgraded and you can have a couple of single ones if you need for nothing

The garage have reported that there appears to be nothing wrong with the coil packs. They have changed the plugs though.

They have said that their two code readers, Bosch and Snap On, are both coming up with the same fault code, P0602, which is pointing to the ECU. This ECU was fitted by Retro Sports Cars about 4 years ago.

Trying to get hold of the garage now to ask for there advice.

But many thanks for your offer which I may still take you up on.

No worries and im sure Chris can fix your ecu as he fitted it

Got a reply from Chris Flanagan, and it reads

Sorry to hear you’re having trouble with your car.

The fault code you are getting is because you have the Kenne Bell tune in the ecu. All cars with a non factory calibration show that fault code. I would suspect its either a faulty coil pack, injector or a wiring fault.
If I can be of any more help please don’t hesitate to contact me.


So Jeff you have a pm re the coil packs.

And replied bob

Check the engine breather pipes that run from each head to the inlet if either of those is holed it can cause rough running and a misfire.

Had one with a strange misfire a few years ago now, tried plugs, known good coil packs and wiring, found it by accident when my finger felt a split ;)

Russ

And posted via Hermes Bob, should be with you sometime next week I expect

I’ve bitten the bullet and ordered the High Performance coil packs from Rock Auto. Going for a lay down in a dark room now.

And me.
Coil packs?
What is so special about them?
And what is MSD an abbreviation for?
Thanks for enlightening me.
Regards David

No idea what MSD stands for. Just the name of the manufacturer I suppose. They can be found on the Holley page.

MSD is the company name and comes from their original design concepts of . ..... Multiple Spark Discharge :D

For what it's worth, my V8 developed an annoying misfire at around 35k miles some years back. Main dealer recommended to change all the plugs at visit one. No change, so I was then told one of the 'Cops' should be replaced as it was faulty. That one standard coil pack cost me almost £300. Drove off and the misfire was still there. I asked for the 'old' pack back, and was informed it had already gone to scrap. They then wanted to replace all the other packs as they were suspect. Cost was to be nearly £2k. I declined and took the car home. I ordered MSD's from the states which cost me around $28 each at the time. A few days after ordering the MSD's I spent the best part of four hours thoroughly cleaning and checking every connector I could find in the engine bay while waiting for the MSD's to arrive.
To my great surprise, the cleaning job fixed the misfire and it hasn't returned( at over £70k miles now.) The MSD's are all in the spare parts bin, but I might fit them one day to see if it helps with the odd little stutters I get when the car is cold. I also read somewhere that the wrong MSD's might damage the engine which put me off fitting them. :getmecoat:

Have the ones I sent over arrived then Bob and you tested to see if that was the problem as it's not been proven yet? If not I personally have waited a couple of days till I fitted the replacements I sent over then gone from there.
You may just have wasted your money

Hermes have contacted me to say that they are on there way.

The coil packs have arrived from Jeff. Now with the garage who have had no luck in finding any. So I’m very thankful to Jeff for his kind offer.

That’s what the club is all about, helping one and other out.

Not a problem, I was under the impression you had also bought a set from Rock Auto before these arrived?

Still haven’t got the car back. Usually the garage are very good but for some reason they forgot about the Bear. Now hoping it will be ready by Monday.

Bob. Short term memory not as good as it was ???

Use this FREE insurance you said you'd look into.--Did you ??--Did you ??.

NO !!!!!!!!

:smilie_re:--Do it now. You said in an earlier post that this forum was all about helping folk.--:shrug:

Well that's what I'm up to.--Now, ball in your court.---:D:D:D

Apologies I have not. Had other things to sort out. I’m at that funny age. But thanks for the reminder, I will have a look, honestly.

What was the verdict then?

I still have not got the car back. I phoned last Friday and was assured the car would be ready Monday. Will be phoning tomorrow and unless it’s not being worked on I will be getting the car home. And I’ll go from there. Possibly getting the AA out to assist.

Bob,

I see your "failed" ebay transaction has reappeared with a "New" Zero rated user. :eek:

Especially as they were "out of stock" :D

Wasn't even smart enough to change the photos :duh::duh:

Chris

Home, but………
 

…………………….. not fixed. The garage fitted the new coil packs I bought from Rock Auto. But the car still has the mis-fire. I collected the car this morning and drove her home. Seemed to be running ok till you put your foot down then she pops and bangs.

So the Bear is now booked in with Retro Sports Cars for Chris Flanagan to work his magic on. She is being collected on Wednesday and taken up on a trailer.
There is a list of other jobs that need doing anyway, so I might as well get them all done.

Then she will be going up For Sale. Rarely gets used and I would rather spend the money on Banana.

I've acquired a similar misfire with the V8 in the last 24 hrs. When warm, runs fine until you try to accelerate and then not happy. Today an engine warning light came on. When I parked her around three weeks ago I left her on a ctek charger. She had been running fine, so I'm wondering what might have happened while parked up? She started first time but it's not the same car I parked three weeks ago.:shrug:

I had a lengthy phone call with Chris Flanagan, from Retro Sports Cars, into what might be causing the problem. In my case it might be down to the spark plugs. I was unaware that the plugs are different on the supercharged cars. The heat causes them to burn out.

In your case have a look to see in any dampness is affecting the plugs/coil packs. Or it might be an injector.

Good luck with sorting it out.

I asked for the plugs to be changed at the last service but apparently the (main dealer) couldn't get the coil packs off to get access to the plugs as the retaining screws were just spinning. However she was running fine until I parked her up, so I'll have a good look this weekend. Last time a good clean of all the connectors did the trick, so worth trying that again, but the engine warning light will need investigation, and new plugs are overdue too. Hopefully just a plug change will revive the Bear for yourself Bob.

I used to own 457 and the only starting/running problem I had was probably fuel vapourization
when starting the car on a very hot day, after it had been left for 5/10 mins when engine was already hot.

When I had no. 50 I had two running problems.

One was, as Big Russ said, a split in a breather hose (I think it went across the top of the engine and had foam around it).

The other was dampness on the rubber boot part of the coil pack and around the sparkplug.
I think it was plug no.8 (at the rear on the nearside).
You would need to remove the coilpack to see the dampness, and see if the sparkplug has any rust on it.

Collected the V8 after it had been parked up for a month due to 1)the misfire, 2) the engine warning light, 3) floppy manual linkage and 4) a toc toc toc noise seemingly from the rear driver side wheel region related to wheel rotation speed.
Started first time. No misfire and the engine warning light had turned itself off.
A friendly gremlin?:bowdown:. Curious the engine warning light reset itself while just parked:shrug: Wish said gremlin had found the time to fix the other issues :} Nevertheless, she's going to be my daily driver for the next few days ( until I fix the sudden misfire on the Astra turbo ). I'd almost forgotten what a great driver's car the ZT 260 is. Now spotlessly cleaned and waiting for the first seagull!

No 50 as tis today .. still wilth me :D

Not sure of my number but it’s a 2004. Been with me since I acquired her for half price when Rover went bust.https://uploads.tapatalk-cdn.com/202...c5e1caa265.jpg
