[QUOTE=TommySSE]How do I check the operating status of the 82 Computer?
Engine running like its on 6 cylinders - step on the gas a little and it back fires through throttlebody, like it sneezed, and pinging like crazy on 93 octane. Was running on regular really nicely getting 20mpg with plenty of power.
I tried unplugging the battery a couple of times hoping it would reboot/reset the computer - no difference noticed. I'm pulling the plugs, wires, dist cap, and rotor cause I saw a lot of shorting between the plug wires. found plugs that seemed fouled.
Using an "action code scanner" (CP9001) - the code pumped out 12 = computer error.
The previous owner removed the cats - so my guess is that the computer may have been tampered with, cause what would you do about the O2 sensor at the cat? my bet is that the computer is looking for that O2 data.
Advice?
Does C3VR forum have a photo library (searchable) for wiring diagrams and other points of interest?

sounds to me your off timming, back fire through the tb seems like timming related. when I did the top end of my 82 I didnt get the timming right to begin with and it also backfired through the tb's.
is just a thought but perhaps your timming chain needs replaced not knowing how many miles are on your car and if it came on all of a sudden I would really look at your timming and check for vacuume leaks as well.
