Backfiring at start up when cold
All of our cars have a start up cycle they go through in order to heat up the catalytic converters. It's a fast-idle for about 20 seconds before dropping down to normal idle speed.....now my problem. After letting my car sit for a few days, it backfires like heck and the fast idle fluctuates...- Donnie B
