Code 21 is coolant temperature high. A faulty thermostat stuck closed or a defective coolant temperature switch could be the cause. Code 43 is Electronic Spark Control. This can be due to timing being off. When setting the timing you need to disconnect the tan/black wire. If that doesn't fix it then the Engine Control Module or Prom could be at fault.
Have a 305 Chevrolet motor that will not go in timeget no change when you pull the est to set the timing?
Whenever someone has trouble timing a Chevrolet V8 engine, the cause for the problem generally points to a stretched or worn out timing chain & gears. Make sure that all timing advance mechanisms are disabled. Depending on the age of the vehicle in question it may be as simple as plugging the vacuum line to the distributor, or as difficult as disabling the advance circuit of the engine control unit. If all advance systems have been disabled and you find it difficult to set the timing accurately, inspect the timing chain for stretch.

What would cause my 1988 Comanche 4.0 to idle OK but misfire terribly upon acceleration?
Answer it could be that the vacuum advance on the distributor is not working. You need a timing light to be able to tell, but when the accelerator is pushed down, this causes the engine vacuum to increase, which should automatically advance the ignition timing. If the hose has come loose, or has a hole in it, the distributor will not advance. The vacuum advance itself also might be bad. A bad spark plug(s) or spark plug wire(s) could also cause those symptoms.
