Backfiring , missing, loading up after cam HELP!! After the cam install I had the true duals put on. The whole way to the muffler shop the car was backfiring, stalling, missing badly but I figured it was the o2's freaking out with open headers. I pick the car up from the muffler shop and its still missing very badly and backfiring. I get it home reset the ECM pull the 02's one of them was black so I replaced it with a rear o2, checked all the plug wires to make sure the're snapped everything looked good so I hooked the battery back up took it for a spin and its still screwed up. HEAVY backfiring on acceleration and deccelartion, and lots of missing and stumbling in between. I have had a thread posted in the Texas forum for 2 days hoping someone would hook me up with an ATAP to see whats going on but have had no response. I was suppose to take the car and have it dyno tuned but it is ruinnig so shitty I don't think it could make it very far without major problems. Someone help me figure out whats going on, right now in dead in the water with no help in sight.......
I had the same exact thing going on. Coil packs on the driver side was on backwards. 98-99 have the coil packs strung together. Check that out. Should be some numbers on them to identify them. Only one of mine had the stamp still on the white part so i figured that was the coil pack that went towards the back of the engine.

take it to a local autozone
most of their locations have a scanner, and they'll print the codes/definitions out for you, for free
if there isnt one nearby, try calling around different parts stores. Surely someone has a scanner
