my car has been idleing at 1500 rpms for the last week or so. i cleaned the old IAC and nothing so went and picked up a new one, once again nothing. so i took off the EGR and cleaned it REALLY! good and nothing, checked all of my vac lines all seem to be good. TPS volt. is .98 and at WOT 4.63. wen i bought the car the kid told me that there is a B-cam in it i am not 100% sure on that fact tho, but if it is i dont see how that small of a cam could make the car idle that high. i am running out of places to check being as i dont know the 302 very well this is my first stang so any help is great thanks. and please no one leave a mess or comment degrading me or the subject please i am only lookin for help not hinderance.
