Problems in Starting up the vehicle

[Raf74]

Hi Good People
Am just new in this forum, and am from Malawi in the continent of Africa. I have my Rover 75 2.0 V6 automatic transmission which I bought in 2011.

Since that time I have been driving without problems until early last year 2019, when I noticed that each time I want to start the vehicle I have to press the pedal down and when it picks up I have to drive like a manual vehicle balance between the brake pedal and accelerator pedal for about a kilometer, without it the vehicle will go off. And the worst thing is that I have to do this each time I want to start the vehicle

After some machine diagnostics, I was advised to change the Idle air control valve, throttle body control sensor, the two sensors that go to the exhaust pipes, I have even changed the actual throttle body with sensors, and also fuel pump, but still the problem is there.

I have just done my routine service, changed spark plugs, oil filter, air cleaner, pollen filter, and engine oil. I buy my spares from eBay including the service kits.

Please I have run out of ideas, your help / ideas are much needed

Regards

Hello Raf and to the club. I'm not sure that I understand what is actually happening.

Are you saying that the engine won't fire unless you depress the accelerator pedal?
Then, is the idle speed too high making it necessary for you to use the brake pedal?
What do you mean by "the vehicle will go off"?

Also, did this fault occur before or after your service?

Thanks, no the engine fires properly but doesn't maintain it's idling level,

By engine goes off I meant that when I crank the starter motor, the engine picks up, so instead of it remaining at it's idle level, it goes down until it cut-off so for it not to cut off I have to balance between the brake pedal and accelerator pedal and at the same time engaging the gear then off I go

Yes it is still happening even after my recent service,. That's why I have decided to ask some ideas from the forum members

I don't know if it's clear now

The plug leads on early engines (where fitted to front bank) can fail, as can the coil packs.

The only thing that I haven't tried to do is to change the plug leads as suggested, but am planning to do so very soon

Thanks for the clarification Raf, it's very helpful.

I don't think that this is plug leads or ignition coils. I had a misfire recently due to a faulty ignition coil. It was quite obviously a misfire and the engine didn't stall at any time.

The first thing I think you should check is the accelerator cable adjustment at the throttle butterfly. Do you have the instructions for this?

I have tried adjusting the accelerator Cable so many times , but still it doesn't work.....but in case there are some instructions on the same which I don't know, please share me, because I adjust the cable the same way we adjust the idling manually.

So please share me the other ways of doing it

This sounds to me like a cold idle fault. I am assuming that once engine is warm all is well?

Partly yes, partly no, because sometimes, not most of the times, even if the engine is warm and you suddenly apply an emergency brake, the engine stalls, sometimes even when doing the free-point-turn, without balancing between the brake pedal and accelerator pedal, the engine stalls
