hey i was just wondering if anyone else has had this problem. i have installed a fmic and pod, and know there seems to be flucuating up and down around 3 - 400 rpms at idle. i have reset the computer and it still seems to happen. will i need a retune or what. the car is stock (exhaust, fmic, bov, pod)
any suggestions would be much appreiciated.
cheers
