It sat in his garage until last year when he tried to fix it up to trade it in. The dealer only wanted to give him $1200, so he gave it to us.
So I get it and it has a check eng. light.
We drove to back from Utah with the light on, it ran fine.

I have it scanned and it had three codes (p1128 and I can't find the sheet on the other two- I know, I know) The diagnostic sheets had possible causes on them and the only thing they all had in common was the O2 sensor and the MAF sensor. I bought a scanner and cleared the codes to see if they reset. As soon as I cleared the codes it idled badly and bogged down when I started off. This only lasted for a minute and I wrote it off as driver error. I drove around for most of the next day when the light came on while on the freeway. I double checked the code and all that was there was the P1128. So I changed the upstream O2 sensor and cleared the code again. Big mistake! Now the car has an extremely bad idle, when I press the gas, it bogs down and backfires, then it will rev up. I can’t drive it enough to reset the light.
I inspected the vacuum lines for cracks or loose fittings and found none. I did find that the wire connection to the MAF was cracked and the wires looked like they weren’t making a good connection. I replaced that and still no dice.

I don’t want to keep throwing parts at this, but the next thing in my sights is the MAF.

Dude you need to scan it and post all the codes present now.More info = better answers..GL KP..
