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?
