So the car crapped out at Houston and then wouldn't run at TWS. Thanks to the LT1 Gurus who shared some brain power.

I changed the coil and ICM at the track; no bueno.

Bought a cable from AKM, downloaded Freescan and peered deep into the bowels of a stock '94 PCM.

The codes for the missing automatic trans stuff made sense. The code for the low coolant temp made sense since I unplugged it at TWS. The other codes (26,27,29) seem to be emissions related.

PCM has the idle set to 600 which is where it idles. I started it several times, cleared the codes, and the emissions codes came back ~ no surprise.

No opti related or other ignition related codes. No PCM fault related codes. Even at 205 degree water it would rev to the limit where it had stumbled and bogged at the track.

Any other ideas?
