got a problem with the car ive just bought it and it seems to be hunting i changed the dizzy cap and also changed the spark plugs and fuel filter but the cars still hunting but the only change ive seen is the revs are a little lower can anyone help its my first turbo and im pulling my hair out its a 1990 s2 escort rs turbo cheers

 

Have you tried the idle position???

If its not seeing this then the engine would hunt on idle.

 

as said or maybe an air leak.mfi r a bugger 4 this mate
