wichita falls,
Texas
I just rebuilt and put in a new motor in my 91 AWD. I have a big 16g, and mandrell bent ceramic-coated o2 housing and downpipe (3"). My CEL comes on only when the car is at idle. If you barely hit the gas, it goes away, until it resumes to steady idle. My MAF has the bottom part of the screen still on it. My o2 wire shows no sign of being burned. The connection seems to be fine. For some reason I think it is the 02, but I also have taken off all my emissions hoses that went to the fire wall to be re-circulated. The only hoses I have are the fuel pressure and BOV one. I am trying to give as much info as I can so you guys will know what I am dealing with. Thanks for any help in advance!
