From your other threads on the same subject it is hard to follow along. The ignition control module (ICM) can do what you are describing. Intermittent … they are cheap and relatively easy to change. You can pull the old one and take it to the parts store and they can test it for you before you buy a new one.

I recently had an intermittent problem where the car died randomly about 2 weeks after my ICM and it turned out to be a bad coil … antoher cheap part that's easily tested.

You can disconnect the MAF and the car will still run on tables. I don't think it will cause a no start and MAFs are expensive.

You'll have to pull your distributor cap to pull the ICM … make sure you mark your wires. The distributor cover has the cylinder number on it. If you have to reinstall it or put a new one back in you will need some more thermal paste under it. The coil is in the distributor cap and you can test it with an Ohm-meter. My tested open when it finally failed for good.
