As others have said you may have a bum throttle body. Especially with those codes.

[SIZE=2]Did you reinstall the old MAF sensor?
Did you use a new O-ring and make sure there are no air leaks into the system?
Is your battery a good one and not ten years old?
The answer to all these questions should be yes.

Yes to all of the above, (will double check for leaks) I'm going to try cleaning the TB mechanism and see if that fixes it.One more question; will the mechanism of my original TB work in the 74mm TB?
