PCM Electronic Wizards and DTC Codes
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?
AKM ALDL Cables Rock ~ Just have to tell DataMaster it's on a USB port

I'll check again the next time I'm over there, but I don't think i have any back there.
I DL'ed the DataMaster software (it's pretty cool) and am getting ready to drop a couple files to Casey.
I had another thought this evening ~ could the catalytic converter be plugging up when it gets hot? I know, I know... "why is that thing still even in there?" Just 'cause.
