Over past 2 years, six or so times, a loud pop, smoke, upon second start of day. (Drove two blocks, stopped car. Backfire under hood upon start half an hour later). Changed plugs and wires at Pep Boys yesterday. The backfire under hood happened when he first attempted to start car to move to a work stall. Scared the mechanic. He had no idea what would cause it. Changed plugs and wires (which is why I brought my car there thinking that was the problem, and mechanic doubted that was the issue but changed them anyway) and sent me on my way. I just searched causes, and found your "How to Fix Engine Backfires in Under 30 Minutes". I am in Tarzana, CA. Wish I were closer to you guys. Any idea how much I may have to spend to get this diagnosed properly and fixed?
have the same problem?
