wierd idle
#12
Is the weird idle a PCM idle relearn? This happened to me from time to time when I had a bad battery and a bad ground connection. What was happening to me was that any time the truck was shut off the PCM would lose power and lose all learned data causing an idle relearn at every start. Since the truck ran on the alternator on the way home the PCM relearned idle enough to idle smoothly until it sat and I restarted it.
Just a thought.
