help with exposive backfires
so to start my car was running fine but i had a oil leak between the rear iron and housing, so took the motor to the guy that built it, turns outs it was his bad not enough sealent. so put the engine back in didn't change any settings on my haltech e8, zero'd the timing out. cranked it over and started getting huge backfires that actually blow the seams out on my muffler. so far ive checked timing agian, its right on. checked all inj conections and order, all good. checked ign order and conections, also good. The number 2 rotor is not firing every time i believe because there is a 250 to 300 degree diffrence in the header temps.
PLEASE HELP any ideas i'm realy getting pissed off.

how is your ignition system itself, not just the order? I had a tremendous afterfire problem (you are saying backfire but I forgive you ) when my leading coil started crapping out. The car barely started or ran, and it sound like a machine gun. I had to give up cranking the car because I heard screaming and sirens after all the constant explosions.
I would check/replace your coils. This is all based on my experience though.

Same thing happened to me yesterday. Rotor 2 was getting flooded randomly. Take out the spark plugs, clean them, unplug your coils and fuel pump and crank the engine for 5 seconds. Put everything back together, good as new.
