he has an intake, and catback exhuast. when he puts it in neutral and is slowing down his car will stall (04 mustang mach 1) he took it to the dealership because his check engine light was on, and it was a problem with one of the sensors in the exhaust, and he asked about the idle problem and they said there was a leak after the MAF, but we couldnt find one when we looked. so i figured it was probably a vacuum leak, so we did a quick check through the ones we could reach in the parking lot and none were loose. now im sure that it isnt the intake doing this because hes had both the intake and exhuast installed for a month or so, and the idle problem has been in the last week. what do you guys think it is?

What kind of air filter does his intake have? Oiled filters are notorious for gunking up hot wire MAF sensors. Take come carb cleaner to the MAF sensor element and see if it helps.

yeah thats what this kid was telling me. (but he says the dumbest **** ever so i didnt really believe him) and he also said there was no cure for it, and that he needed to take off his intake and get a new MAF. and yeah he has an oiled filter.
