Electronic Spark Control disconnect is under the heater, right side, on the floor, just under the top edge of the carpet. You will see a single wire with a connector in the middle.

Cool What fans do you like?

I have a 94 S-10 Blazer with the 4.3/W Vortec, and I'm trying to settle on the best means to cool the radiator. I have always hated the factory clutch fan (blows too much and robs too much power),...

Spark advance is controlled by the ECM/PCM through the ignition module. When you have this problem, do you check the timing to see if the spark advance is working, or stuck in base timing mode?

Electronic Spark Control is stuck in retard mode. Maybe a bad ignition module on the distributor.

Code 42 will generally set after setting base timing, because the Electronic Spark Control has to be disconnected under the dash to set timing. I'm not sure the problem lies there.
Any...

Anything that triggers a code will cause the SES light to come on, even if the problem doesn't persist. Stored codes are kept for 50 key cycles, even if they don't reoccur. You might need to clear...

You've mentioned you have run the truck low enough on fuel to cause a stumble when stopping. The flat GM fuel tanks are poorly baffled, so a lot of sloshing occurs in the tank. Even with fuel...

Check Fuel Injection

The poppet valves on the central port injection (CPI) can become clogged or stick, preventing fuel from reaching each cylinder. Have you run any fuel injection cleaners (Sea Foam, Gum Out?) through...
