Well for the past two weeks my car has had this problem... At first I thought it was the AFM, so i checked it with 2 different ones to no avail. So o then thought it was a connection problem in the loom plug, but last night, Me and Hippy tested all the connections with a multimeter and we found that they were fine (eventually).
So now im at the stage to think the ECU is buggered So ill be trying a new one tomorrow to see if that fixes it.
However what has got me really confused is that sometimes the car runs fine, revs perfectly, and about the other 95% it runs like crap. Could it still be the ECU even though the problem goes away and comes back???
Sooo confused....
