MG ZT-T 135 2003 goes off high revs
 

Hi,

First of all want to apologize for my bad english, i'm a Portuguese recent owner of a MG ZT-T 2.0 CDTI 136cv of 2003 with 230.000km.
I'm pleased with the buy as it just had one owner until i bought it.
The problem appeared today, as i was travelling with my familly and when entering a high way i've puched 2nd gear a litle bit more and at about 4000 rpm it basicaly loose all power and did not response until i pull out and turned off and started again the engine.
After that as i was far from home, i did the trip with carefull and didn't noticed any failure neither smoke but just traveled at about 130km/h at maximum.
So anyone can help to figure what could have been the cause of it?

Thanks.

Diesel engines normally don't like to be revved that high. It was probably just complaining.--:icon_lol:

There is no advantage to treat the engine like a petrol engine as the diesel motor will put out its maximum pulling power at around 3,000rpm. After that the power starts to drop off and you will actually accelerate faster if you change up a gear.

If it is running OK at the moment you probably haven't done it any harm.

That is a classic sign of a leaking injector, it's time to perform a leakback test ;)

Brian :D

It was only 4000rpm, no issues at all going over that if everything is as it should be.

Thanks Brian, I'll start for checking that

Totally agree. The injector probably couldn't keep up with the demand at high revs with a leak.

Just trying to save the guy some money as 3,000 rpm is well over the speed limit in top gear. --( even in Portugal. --:shocked: )


PS. 230,000 km mileage on the engine.---' bout as old as I am and I hate to be revved.---Soon run out of puff.
