My service engine light has been on and the car needs to pass emissions. It’s a cylinder 6 misfire and we cannot figure out what is causing the misfire. A new fuel injector was put in, ignition coil, spark plugs and wires so far.
Have you verified that the fuel injector is being correctly pulsed . . . a noid lite kit would give you many answers
A compression test would also not be a bad idea
What engine?
3.1?
3.4?
check engine light on steady at idle?
check engine light flashing at idle?
