Question about Cars & Trucks
You may get some popping with a leaking exhaust but not common. Sounds like you're in need of a tune up. Spark plugs and new wires to start. The flames are due to unburnt fuel from mostly a miss fire. Try a simple tune up first, also make sure you have a new air filter to help the motor breathe easier and save money at the pumps. Be sure to check and replace any old/cracked vacuum lines as this will cause poor performance too. Hope this helps start you in the right direction.

I had the same problem, thinking it was bad gas, or bad wires, or even a clogged fuel filter, had the engine checked out by a reputable gear head. A head bolt broke, then a intake lobe from cylinder #4 spun round thus causing your car to constantly backfire, also check to see if your head gaskets aren't blown (water-n-oil), all these were found once the engine was disassembled. Good luck trying to find a good used 3.4

My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.
