96 Legacy 2.2. The spark plugs go in above the valve covers, Not through them. It may be a coincidence but the problem started after switching to Red Line oil. I used other full synthetics before, (Amsoil, M1, RP) never had an issue. Red Line is also the only one that quieted the ticking valve lash also.
I won't get a check engine or a misfire if I baby it. There are times when I must accelerate briskly to merge into fast traffic. If the motor's cold (first 4 miles and under load), I will get a P0301 code for the misfire in cylinder 1. That is the only cylinder that has the issue.
While replacing spark plugs I was shocked by the #1 boot as well as the outside of the spark plug drenched in oil. The other plugs are fine. The business end, (electrode inside the cylinder where it sparks) is fine.
So I replaced plugs and wires. No help. What is the deal?
I know it's an older car with a ton of miles but I like it, I wan't to make it well.
