I have a p0304 code which indicates misfire on cylinder 4. The car seems 2 shake once in awhile and fuel economy has gone down significantly. I already changed the coils for cylinder 3 and 4 but still no luck. Can anyone help on how I could fix this?
p0304 code, low fuel economy now, car starts to shake at times, and check engine light
is still on after replacing coil for cylinder 4 and 3 and reset.
Is your car up for recall on your igintion switch?And if so has it been repaired?
yes and it has already been repaired
If 1 and 2 are getting fire,may be bad crank sensor or your ECM.
I also have a error code that indicates a lean to rich sensor threshold fail
