hi guys,
we installed a brand new eforce p/n 1562 into 2014 Camaro.
installation was plain with no issues.
but has soon as you drive the car a little bit there is misfire on cylinder 7 and 4
I suppose the problem is on 7 and 4 is only following
already checked wiring for pinching all ok
already checked spark plug (gapped to 0.35) all ok
already swapped spark plug wire ok
sprayed carb cleaner all ok
I removed spark plug and 7 one is very dark with deposit, 4 is ok like others
spark plug are OEM ACdelco
SCT tuner is alredy update to last sw
any good idea for us?
any tip?
thank you so much!
best regards
