Default What causes backfiring?
All of a sudden, my car has started backfiring almost everytime I change gears (when I'm winding her up). I just finished changing out my header gaskets to copper as I had a leak. I also lost one of the threaded plugs that go in the heads, which I replaced this morning. It seems a bit coincidental that the backfiring. Performance is fine (she idles and winds up smoothly). But it's a bit embarassing when I get on it and I become a "drive by shooting" suspect. Any ideas?
