Electronic Spark Control runs a self check and it failed the check. You need to replace the HEI module inside the distributor, check all the wires and connectors for rust and clean as needed.

Having multiple intermittent problems


I guess the overall answer is yes it could be the ECM.
Code 16 is high or low system battery voltage.
Code 21 and 22 are both for the throttle position sensor.
And code 43 is for the electronic spark control which controls engine spark timing.
The ECM grounds various relays to make things happen such as turning on the cooling fan. So a faulty ECM could cause all of the symptoms. But so could a wiring problem in one of the harnesses.
Especially a ground problem somewhere.
If the alternator suddenly starts overcharging the system the ECM can shut down the car to protect the circuits. Unusual, but possible.
This info may not help much, but somebody is going to have to test the circuits when the engine dies or when the symptoms happen.

97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m


Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

yes you should. my brother had this same problem a few months ago. and his cavalier would randomly shut off on him when it wanted to. it can get dangerous if ignored. he ended up replacing the tps (throttle sensor) and the o2 sensor and it started running decently

Autozone and similar stores will check the codes in the computer for free usually. That is the best place to start. Other possibilities are Engine Coolant Temperature sensor (saying the engine is cold when it's not) or excessive fuel pressure (bad regulator or blocked return line)

the pcm may have a cracked board, i had an 88 cavalier z24 with the same problem, replced the ecu and it ran fine, the problem is that the boards inside the pcm crack and lose connection, the next time it acts up open the glove box and try tapping on the pcm, if the car responds at all, the pcm is bad
