Clear the codes (they could have been there a while), see what comes back and note what your system voltage is.

I have tried several times n for some reason the codes will not clear... I had AutoZone check my battery and alt n the system was at .14.4 if memory served me correct! Lol
Also I had put a new o2 sensor when I put the car back together. What really gets me is the 51 code.

Your not going to easily cure 51 by clearing it. That is a checksum error. Corrupted calibration error or one of the two flash chips failing.

what kind of scanner are you using?
i bought and then returned a innova scanner awhile back and it gave me all the wrong codes. I ordered one of the obd1 usb cables and used datamaster on my laptop to scan it and instead of having 9 codes that made no sense i only got 4 codes.

IDK what is up with the Innova scanners, but I have seen lots of people with weird results from them. I'd use something else.

I done see a few different post where them innova scanners r junk. What I'm gonna do is swap the pcm out with another this weekend n see if anything changes... Now I do have a 52 mm throttle body n bbk shorties on the car now. Do u think that the bbk suck n burning up them new 02 sensors? Because I'm gettin a lean n rich code which is weird to me. I done checked everything else I been throwing parts at it since day one. Also this is my first ob1 car n I been lookin into buying a USB n get some software to look over anything. Which would be the best to get?
