OK well Coil 1 is definetly after market. The spring inside is almost to the bottom, the other 3 the spring is maybe 1/2" from the bottom. It also doesn't have the markings the other 3 have.
So yeah. (1 left to right facing engine, closest to passenger side).
But replacing the plugs went easy. Didn't have access to the obd computer one. My orange obd reader doesn't link to this car. It does to my other car. It's odd. So couldn't clear the pending yet. Will try in a few days to.
I took apart each one. Each spring looks fine. Boot was dirty at top. Cleaned it with a clean cloth. Other then that they look fine. Just unsure how good that 1 coil is.
