Hi,

My cars not been running quite right for a while. It doesn't accelerate hard from under 2k revs any more, instead it ejects a big could of smoke and then gets going from about 2300 rpm as it should. Had the car on a rolling road on Saturday and it made 218hp so the power is still there, just not at low revs

I was wondering if a dodgy MAF could be the culprit? I've unplugged it and been for a short drive and it made no difference. Is this alone a sign the the MAF is no good?

If the MAF was working and I unplugged it then it would really affect the performance right?

Any thoughts appreciated!

Joe

With it unplugged it should of run better so I'd say it's not the maf. Could it be sticking vanes on the turbo??

The MAF could be mapped out by dark side, ask John

 

Did the EML come on with the MAF unplugged?

Yours is a BLT so smoke limiter is based on the MAP sensor. Unplugging the MAF will make no difference even if it was faulty. I can confirm this 100%

Well that solves that, I didn't have any EML light either, but that was mapped out with a EGR delete anyway.

Back to the drawing board...

Thank you

Do a fresh group 11 and group 4 log from 1500rpm in 4th and we can compare to previous logs to see if there's any difference.

Your EML should still work though,for all other sensor/ECU faults,they only stop the missing EGR from lighting it up.

 

Should light up when you switch ignition on?

The fault code relating to the EGR has been removed. So eml still works but just ignores the EGR error.
