"Every so often I get a popping sound from the exhaust when I start the car and accelerate. Almost like a hesitation. What I have to do is accelerate hard a couple of time and it goes away."
Mine does not really pop, but you can hear the exhaust gurggle, not when I accererate, but when I let off the gas. It does sound like unburnt fuel igniting, but just checked my mixture last week and its right on the money. I suspect it is just my exhaust system allowing you to hear more of what is going on. Anyone else with headers 100-cell cats and a high-flow muffler hear that sort of thing?
