hi, ive got a e36 2.5 m50 engine it was fine i give it new plugs and filters, oil etc. but the day after it ticks over fine but seem to be holding back and have a missfire when on load.ive Had a look over everything seems ok ive have a look at the coils and number 2 was down so bought a new 1 then number 6 went down so i put number 6 into 1 and 1 into 6 it ran fine for 5 mins then missfire come back, so i unpluged the coil one by one and it showed number 3 was down and number 1 and 6 was fine.
Has anyone had this before any common thing i should b looking for thanks guys
