Getting a P0100, no other codes, car goes into limp in or starts hesitating. Stock air box, ZZP tune. Checked and tightened all clamps from air box to intake manifold. Air filter is new, stock GM. Replaced MAF, and Cam Solenoids. Verified continuity at MAF connector. Swapped in ZZP airbox to turbo silicone pipe, no go, swapped back to stock. Best it will do is about 20-30 minutes of driving before throwing another p0100.
After reading the forums, tracing the wiring and replacing the ECU are all that's left, that I can tell.

I need to trace back to the ECU, tried matching the colors at the ECU, got tired of that real quick.
Is there a wiring diagram, or better yet a pin out on the ECU so I don't have to trace the wires through the harness?

My Chiltons book has "wiring diagrams" but nothing about the ECU and shiz that connects to it of course! I can troubleshoot the **** out of the dashboard lights though!

Thx for the info!! Nope, I don't have a scanner. But now I just realized I didn't check that fuse. Just checked fuse is good.

Wiring is good, would have taken less time if i'd have realized the left side of the car was the connector to test not the left hand connector as I was facing the ECU! That's what I get for not reading closely. Looks like the ECU is at fault.
