yeah thats what i was thinking but ive prolly put close to sixty seventy miiles on traveling to and from work since the intake was put on?, is thihs something you guys had while testing or does anyone else have anything like this going on. I almost sounds like my buddies honda when it needed an idle switch or something like that, not sure but it would rev up and then drop the revs real quick and keep doing it, my car does it once or twice everytime i stop, revs slowly climb then quickly drop off. hopefully it will go away
