    Greetings I need some help Astra 1600 will go through fast idle test but will start to miss and not run evenly on idle have checked for head gasket thats ok inlet gasket ok vacuun pipes ok tested dis pack with snappy ok tried different leads and dis pack no change Plug on no 4 black and sooty compression test ok o2 sensor switching ok injection pulse 3to 4 ms o2 integrator 129 All I can think is that no4 injector is over fueling slightly which is more pronounced on idle If you have any thoughts please reply Kevin
