Hey guys,

Curious of a car can ping at idle or extremely low speeds (almost idle) I swapped out my MAF setup and the car is getting more air and it was already running rich to begin with so I am thinking this pushed it over the edge. No check engine lights or anything just a really, really loud knocking type noise and a weird "drone" type sound when you let off the throttle (using the throttle body to rev the car)

Thanks.
