I'm throwing a #4 cylinder missfire after running Seafoam, which one is number 4? I don't really feel like taking all the plugs out to see if they are fouled...

Thanks

EDIT i think i figured out which one it is...back one on passenger side?

Does the car run fine? if you go up a hill at 1500 rpm's or so doe sit buck and misfire? if not you probally don't have a misfire anymore the code was probally set while you were seafoming it. This happens all the time when we do this type of service at work, for this reason if the car has to go for a state inspection ( obd2 code scan) we do the service afterwards becuase you can set codes while doing it.

Now if the car is running rough pull that plug out and clean it really well with some brake clean, that stuff works pretty well
