this is a frustrating problem....
92 gxe automatic
every once in a while (maybe twice in a day, don't drive the car terribly much) i get a weird noise coming from under the hood. sounds as tho the car is backfiring, but not at the exhaust, sounds as though it's coming back into the intake, or throttle body. there is one pop, moments after stepping on the gas (not stomping) to leave from a light or other stop. You can feel the car hesitate, then the pop, then car accelerates as normal.
cap, rotor, wires, and plugs are all less than two months old. only modification is a permanent filter on the intake. (not wishing to start a new k&n vs. paper filter string here)
not sure if this backfiring problem is harmfull, though i know it isn't a healthy condition......any advice is most appreciated.
