Engine Performance problem
1997 Opel Kadett 4 cyl Front Wheel Drive Manual 230000 miles
I drive a Kaddet 200is and recently did a service on the car, replaced the idle adjuste (ICV) Fuel pump. The car starts fine but sometimes it idles irregular. When I drive and some times in hi rev's or in low revs the car would start to jerk allot. If I press it past the 4000 rpm mark I struggle to get power and the car misses allot. Also when the car Starts up and I give it a small rev it would bacfire through the intake manifold.
Any ideas What to check Or What can be the problem? Can it be the fuel pressure of the fuel pump caus it to happen?
