I have an 03 GT with no mods..except a Flowmaster cat back system. When the car is idling it sounds as if the idle picks up around another 100rpms every 15 seconds or so at idle. when the car comes off of the +100rpm idle it almost makes a pop noise that I can also feel at my feet. Does anyone else have this problem? And is it really a problem or does it come with the territory?
