sound like the same kind of sound you are hearing, but it comes from somewhere more near the rear of the car. like someone took a sledge an hit the underside of the car.

no, it;s not backfiring. i verified this. the system that pressurizes the air ride shocks is not hooked up or even working, so its not that. there is no other moving part back there, when the car is not driving. this is before i even shift into drive, and i am not revving it.

any idea whatsoever what this could possibly be?

exhaust blockage? fuel lines pressurizing and moving? brake lines doing a similar thing? trunk release solenoid? fuel door solenoid?

i can't think of anything else plausable.

plz help.

More likely the exhaust system grounding and it moves when the engine rocks at startup....
