You can also pull the negative cable and short it to the positive post which is still connected. It'll reset in about 10 seconds.

Rather than do the 3 30 minute key on off reset? Same results?You can also pull the negative cable and short it to the positive post which is still connected. It'll reset in about 10 seconds.
Yep. Maybe you're confusing that with VATS?Rather than do the 3 30 minute key on off reset? Same results?
What light switch is connected to the ECM/PCM? Which capacitors need draining? All you're doing is wiping the volatile memory (RAM) in the computer where STFT/LTFT (Int/BLM), etc live.Turned the light switch on for about 20 minutes. Reconnect the negative cable and started it up. Definitely made a difference in the way it runs.
You nailed it. I got a result. Drove it off and on for a day. When I shut it off for several hours, back to the same problem.Sounds like you got a result but personally I don't think doing a "hard reset" has fixed it. If it acts up again you may want to check the ECT sensor.
