TRY CHECKING THE WIRE CONNECTORS ON THE PCM WHICH IS LOCATED ON THE PASSENGER SIDE FIREWALL. IT HAS THREE LARGE MULTI-WIRE CONNECTORS HELD IN PLACE BY THREE BOLTS. WIGGLE THE CONNECTORS WHILE TIGHTENING THE BOLTS CAREFULLY SO AS NOT TO BREAK THE FRAGILE PLASTIC ENDS. HOPE THIS SOLVES THE PROBLEM. KEEP ME POSTED PLEASE. THANKS FOR USING FIX-YA. GOOD LUCK

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

Nornally reson for backfire is when intake Valve open Internal combustion in Cylinder. Pls Check Your Ignition Timing & Valve Timing. ( I think Your Timing Advancer is Defect )

your problem may be a faulty head or valve seat allowing antifreeze to seep into the exhaust while accelerating or it could be the result of unburned gas try a can of gas treatment or octane booster or a tune up hope this helps.
