Have you pulled the codes yet? That would be a good place to start to see if you have a sensor malfunction or a wiring problems like poor grounds.

OK here are the codes 116 ECT outside test limits 173 HEGO always rich 213 spout circuit open 224 Erratic IDM input to processor 411 can't control RPM During KOEN low RPM 536brakeon/off circuit failed 538 operator error 565 canister purge failed. But has been plugged back in 632 overdrive cancel switch not changing 636TOT sensor voltage out of self test range

OK 116 Engine coolant temp sensor outside test limits, so either the sensor is sending an incorrect reading or there is a wiring problem with that circuit, HEGO always rich, possible fuel pressure regulator problem or timing retarded, 213 spout circuit open, there should be a shorting bar, see pic, in the spout connector that you take out to set base timing, then put back in after the timing is set, 224 could be a bad ignition module or distributor pickup coil, if they have never been replaced then now would be a good time to do so, 411 is the Idle Speed Control valve, remove and clean both the valve and the ports, 536 means that the ECM did not see a brake light signal during the test, 632 OD cancel not changing, 636 trans oil temp sensor out of range, possible bad sensor reading or wiring problem on that circuit. so 536 and 538 and 632 need input from the operator during the running test, when you get the one beep or flash then you need to goose the throttle, and the tap the brake and push the overdrive button on then off, you must do these as fast as possible so the ECM can see them cycle. I hope this will help you with going further on.
