Not sure if anyone can help, but Daughter has a pretty well undriveable car at present.
It will start and run perfectly when cold, sounds great. But after a few minutes, the idle speed jumps to over 2k rpm, and power just drops off. It will not rev up very high, just fades and won't pull.
I've cleaned and checked
MAF, resistance seems ok on the temperature sensor as it warms up, I've cleaned out the idle air controller, and checked all vacuum hoses etc. To say it's frustrating, would be an understatement.
I can't find an egr valve, does it have one?
And ------ any ideas?
Cheers,
DF
