I suggest that you have the system "live data" scanned, that way a person can see in real time what the sensors and the computers responses are at any given time, you could have a slight intermittent open in one or more of the sensors, like the TPS or ECT.

Yes you can do a live data test on an old OBD 1 unit it just takes a little longer to find problems.
