I'll just add to the list... I used to get the POPPING in the exhaust when I let off the gas on my olds. I am to understand it's actualy your exhaust igniting as it gets fresh oxygen from the outside air. I used to get it bad when I had a leaky header seal... once I fixed it it went away.. I dont think it's BAD for anything so much.. I thought it sounded kinda neat actualy.. it was a nice grumble when I let off the gas...
