    when i rev her up in speed and then back off and let it idle down I occasionally hear some back fire. Is it normal or some firing issue or exhaust leak. Just want to know it's not a problem or not. Please let me know if anyone else can hear it to on theirs... Much appreciated. I have the 8 sp auto

    It's just say'in don't let up, keep feeding me gas! Lack of much of a muffler allows us to hear all. Sounds normal.

    I get it once in a while when slowing down or reverse parking or just parking but it happens like once a week or none at all. Normal to me

    It's excess fuel igniting in the exhaust. Normal and cool.

    Normal, I'll actually throttle in the garage before shutting it down just to hear it :)

    revving a car is not good for it. and the noise you hear is normal
