I did a Heads and Cam swap and now I am getting very upset with it. I knew there might need to be a little bit of work but not all of this. When I was on my way to work this morning I just checked my trouble codes again and now I have a few more. I am almost at this point wishing I never did it. If anyone has any Ideas on how to fix my problems please post.

New Codes from this morning:
18 - Injector circuits
51 - EEPROM program error
41 - Ignition control circuit, open
42 - Ignition control circuit, short or grounded

Codes from the first night a few days ago:
44 - Bank 1 (left) O2 sensor, lean
64 - Bank 2 (right) O2 sensor, lean

I dont know how else to fix my car. Fuel pressure is 45 or 46 PSI (Aeromotive Regulator). New NGK TR55 plugs, New CC "R" Lifters, New push rods (chromoly one piece), OB1 Conversion, Lucas 28lb. Flow-matched injectors. I am running a CC306 type cam, Stage2 LT1 heads, Matched Intake, and Duel 60mm AS&M TB. Which I bought off a friend. They came off his car and the computer was tuned then. The only change I made was I am running 28lb. injectors compared to him running 24lb. So if there were any problems with tuning it should be froming richer not leaner. If you need any other info please ask. Thanks

I used to get those first group of codes back in the day. Finally that just up and left.. i dont know why but it seemed to happen possibly because of a failing opti. I noticed this only occured on startup when the motor would fire up and die immediately. Id try again and usually it would stay running on the 2nd try.

The lean codes are interesting. You need to get some datamaster logs to see whats going on there.

I hope it's not the opti. Are there any other Ideas.

The first group of codes are usually opti related. Check the harness.
