i own a 1989 lincoln mark vii lsc, maybe someone out there can help me or encountered a similiar problem. First of all car idles rough also stumbles upon acceleration, occasionally backfiring. At first i thought timing chain, but it checked out. i also pulled the spark plugs one of them the #5 was fouled, and i found fuel in the crankcase. obd 1 codes koeo 34, 31 koer 91, 34, 12 egr has been replaced, along with position sensor, also idle air control replaced, these variables have been removed seems like a leaking fuel injector to me, i never checked fuel pressure, dont have a gauge. oh by the way fuel pressure regulator seems ok (no fuel in vacuum line) Any help or input would be appreciated. i dont have much experience with computer cars, what would be the best way to go about solving this problem without throwing money at the problem. any similiar experiences out there ?
