    Yeah, they are all cleared now even the evap, but i have the permanent codes from the cylinders that used to be used for the AFM/DOD. So i was thinking of removing the ls2 valley cover i plaved and reinstall the AFM VLOM to hopefully trick the computer its still plugged in to AFM.

    Help me find the SNAFU

    Those would be the tie rods. but we found the issue. The Chassis Support bracket, the big metal brace under the oil pan was not torqued down and was causing this.

    Oil pressure sensor HELP!!!! - SOLVED
