Hi, I’m Ron and I can help you.
I have been in the auto repair business with my own shops since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. In most cases when you have a problem with the way the vehicle performs, specialized tooling is required to acquire computer data/information or engine testing results. We didn’t build these complicated vehicles; we just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. I am also going to direct you with the fastest, easiest and most common things to check first. Please be patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.

It's located right after the MAF in the air tunnel.

Thanks, Ron

im reading that my model has it built into the MAF and i have already replaced that a month ago and am still getting the code. i did see a spot in the intake where the IAT would be but i was reading the IAT has a 2 wire connector and the MAF would have a 4 unless its my model which has a 6 wire MAF connector. after being replaced why would it keep the code up?

Some were built into the MAF, but your says it's in the intake plumbing. There can also be a wiring issue or a bad computer too.

thanks again, and please don't forget to rate me and keep this link in case you need me again later on.
