Thats kinda what I was thinking. I am about to put another sensor and a MAF in this weekend and hopefully it will all go away.

LOL well I kinda figured you weren't out side at -27... Its obviuosly not reading correctly and may not be reading the proper flow of air going through it. Same problem with the O2 sensor if its not heating up properly then It's not functioning properly.

BTW Just in case you did not know, Always make sure the vehical is up to it's full operating temprature while your checking sensor functions with a scanner.

Sounds like you did but I just want you and others to be aware in case they did not know

Yeah I drove it about thirty minutes to get to the shop. Could just the MAF make the truck run really bad like it has a miss. Also, could the MAF cause the computer to throw an O2 code? Or is this just my O2???

Maf would cause it to run like **** but the fact that the one sensor was only reading 35 Degrees and the codes I would say its bad too.
