LS3 Backfiring at idle Hoping for some opinions and knowledge to help troubleshoot an issue with a backfiring/popping LS3. The back fire only seems to occur at idle after have recently changing all spark plugs to AC Delco 41-110 and replaced plug wires with the summit racing ceramic boot cover plug wires since the older wires had been burned even with sleeves on the wires. Plug wires have been checked over and over to assure theyre secure, could this backfire be caused from bad coils, or maybe injectors?
