Outer Limits 4x4 Board

i cannot stop my cruiser from backfiring!
at idle it is sucking fuel out of the main jet somehow, its idling erraticaly and just being a pain in the arse

any suggestions?

Try checking your timing I had the same thing also with some pre ignition where once you have turned the truck off it wants to keep running. Did the timing and it is fine now. hope that helps
