I have an update on the car and what I have been doing.
First off, the car started to fail the next day after I was at Gordy’*. (Figures, they never fail when the mechanic is there). In addition to the other items that I have done, I have metered wires from the Crank and Cam sensors to the ICM and to the PCM. I replaced the plug wires, while the car was running, I sprayed the circuit board for the PCM with circuit cool, and I reseated the EPROM.
I talked to one person that worked for an electronic repair shop that was under contact for Delco to re-ferb PCM’*. He stated that Delco had a problem from 86 to 95 with cold solder joints. To test for this, with the car running, give the PCM a couple of good hard slaps with an open hand. If the car acts up, replace it. Well, it did not fail.
I talked to the Service Manager at the local dealer. He stated that generally 4 items cause the 341 and 1361 codes; Crank and Cam sensor, ICM, or the PCM (in that order).
A couple of days ago, I replace the PCM. The car is running just fine. I will wait a couple more weeks before I am convinced that the problem is corrected.
