Engine backfires on cold start passenger side
Engine will backfire like a loud pop on passenger side on cold starts. Like sitting all night. Once it does this it will not do it again till another cold(like overnight)start. Right like it gets cold in Fl. Once it does this car runs fine. Idles at 675.
Replaced plugs and wires. No differance. Tail pipes are clean. Car runs great except for the one pop on start.
Pulled codes B2206 H B22605 H U1016 H U1064 H U1094 H.
When they put the long tube headers on they orderd for 98. My is a 99. They had to reroute the AIR pipe would that make a differance? It didn't do it right away.
Also after pulling the codes and pushing reset they don't go away.
Thanks guys for any info.
