Title: Engine misfiring....
Post by: Greedy on 20 June 2007, 11:24

I have just bought a VW Golf 16v GTi. The car has been missing slightly tho. When idling the car seems 2 rev by itself and doesn't seem to stabilise. Also when driving the car if your foot is just on the accelorator and no more then the car will start jumping as though u had "kangaroo" petrol. Any ideas as to what might be wrong with it?!? Many thanks.

i'm not 100% sure on ABF engines, but if its in the same place as KR 16v's it should be here!
EDIT. should be a kr...

not sure if mk2`s have crank sensors or not but if they do that could p[ossibly be a cause?
