Hi all! The car has 145k miles, bought it 2 years ago with 124k. I was driving it on the highway and it developed a misfire. Threw those codes. I disconnected the coils 1 at a time and determined it was cylinder #4 after i unplugged the coil. So i figure bad coil, of course a new one made no change. replaced all the plugs also, still a misfire. Plugs i took out were NGK, maybe originals? Any help will be much appreciated. From left, cylinder 3, 2, 1. Cylinder 4 plug was blacker than these, I suspect from not firing.
