I recently had a problem with an 89 240 with similar symptoms. The AMM was the fault with mine. Do all the connectors in the plug look to be in good condition?

Does the behavior change with unplugging the AMM and trying to start it cold?

I would guess that the 93's have a coolant sensor that keeps the ECU supplied with the current engine temperature. You can check its function at the plug on the ECU. The resistance values are in the FAQ's.

I checked mine for being in specs when cold and then replaced the connector and started the car. I ran it up to operating temperature before shutting it off and once again pulling the plug at the ECU. Putting the meter back to the correct connectors allowed me to check the resistance at operating temperatures and then monitor the change as the temperature fell.

As long as you have a digital meter handy you can check the voltage fluctuation of the O2 sensor while the car is running. Again the procedure is in the FAQ's
