Checked wiring all seems good what else could it be Compression is also good ad fuel pressure is 60 psi

Hi there,

Take that #8 coil and replace it. Since you still have a misfire and it's not on #8 that coil is failing and no good. It usually takes the right circumstances for it to fail. The computer can't pick it up but since you no longer have a misfire on #8 I would say the coil you removed from there is your culprit.
