All those parts but not a new MAF sensor? That's exactly what mine was doing until I threw out the aftermarket one in mine and replaced it with a new AC Delco model. Cleaning the old one didn't help and I couldn't see anything physically wrong with it either. Soon as I stuck the new MAF sensor in, it ran like a champ and has been for the last 8 months. I also had thrown a lot of other parts at it.

You may be right, as i was installing the cai intake last night, i was scratching my head wondering why i was re-using the old maf sensor...i'll order an ac delco one now...thanks brother

edit: has anyone cut out the screen in the maf sensor? seems like it constricts a lot of air from flowing

Yeah @Fosscore I agree the constant bragging about the weather is getting old. Of course we don't hear any of that when the rest of us are having our summers and you're miserable! hahaha. I've been in that part of the country in the summer, and all I can say is no thanks.

Come up to Alaska where the mosquitos are the size of small birds.

Alright points taken.... I'll say no more about the Florida weather. :rolleyes:
