I would check your wiring for cracks or breaks around the MAF. If everything looks good then replace the MAF, and then reset the Comp. You should be good after this.

Yes unless you want to stop over later and I can do it with my scanner and you won't have to loose your settings. Let me know I get home at about 4:15PM.

Ok guy'* I am on this one. I just met with Jason and checked out his car and scanned it. Well when I first hooked it up the MAF and O2 were not reading at all. So we went under the hood and started checking around and everything looks fine from what I could see. So we talked for a bit and then with the car running and Jason started to tell me about his steering wheel problem where he touches any button and it turns the radio off. Well this time it stayed on and so he kept pressing around until it finally shut off. However when the radio shut off the car instantly started to idle like it had a 325 duration cam in it. Jason said hey look the SES light went off (it was on the whole time before this) so that means the MAF is working now. So I put the scanner back on it and got some readings which are below. The O2 still was not working and is brand new Bosch. I told him to get a Denso we can throw in and he can take the Bosch back.

MAF while working at idle was bouncing between 1300 and 1500, I bliped the throttle a little and got it up to 44000

O2 not reading stayed on rich

LT fuel trim stayed at around 144 - 150

ST fuel trim was at around 128

I have an extra throttle body with all the sensors in it that I told him we can try. I also told him we should probabally clean his ground busses. Any other suggestions are welcome.
