what causes the #1cylinder to misfire
Changed plugs, oil and filter, fuel filter, and replaced 1 of the 2 coils in the coil
pack. Checked compression on all 4 cylinders and it was good in each. The #1
cylinder spark-plug is always wet with gas after running the engine so it seems the
injectors are good. Do I need to buy the other coil and plastic housing they sit in?
Both of my service engine soon lights on both sides of the instrument panel are
on and my trac off light is also on.
if U have the Quad 4 engine- what color is the coil housing. if black- REPLACE - if white change other coil
I have a 1999 pontiac grand am gt, i have changed the spark plugs and wires, fuel filter, TPS,IAC, and the purge valve.... and its still misfiring. It turns on and drives but when i get to a stop sign or to a corner to turn it turns off. I dont know what else it could be..
