My car is overfueling, causing Kanagrroing between 1800-2000rpm.
when I throttle on, it stops. The car smells of petrol on start up. When I Fitted my K&N directly to the AMM, it stopped, becuase it was getting more air. I dont like the affect this has on torque so took it off, put airbox back on. The revs are slow to comedown, and tickover is a bit lumpy. However when the car gets going, its fine.
Ive done a search, and lots of things have been mentioned, so I dont know if giving extra details will help a more acurate diagnosis.
