Miss firing or ECU problem.

Postby oLemurs » Tue Nov 07, 2017 8:46 pm

So as the title states i have some sort of miss fire honestly it sounds cammed but im pretty sure its not cammed, it dosnt sound like a bad plug or bad ignition coil, i was maybe thinking bad ignitor chip or MAF. its running REALLY rich i mean black smoke some times, a** you can see in the first vid i rev it up while cold (idgaf im diagnosing) i have a new FPR set to 42 lbs on idle, and a new coolant temp sensor. my mind is boggled because i dont want to go out and buy parts that i dont need thats why im asking you all if you had this problem and know of a fix.
