I’ve started with my valve covers and replaced them due to cylinder #6 having oil in them. Once installed I replaced all spark plugs but what i’m realizing now is i didn’t clean the oil up in #6 before taking the spark out. is that fine ? Also after rechecking gap and coils put them back in and still giving p0300. not sure what it could be since i didn’t touch anything else. i’ve done the idle reset and the ecu reset and it sounds like it’s “cammed” or even like a wrx. at driving speeds seems fine with a more sensitive throttle but coming to a stop it sputters and eventually dies thanks if anyone can help
