Replaced battery and alternator, left shop and returned 100 miles later with up/down idle and stall at stop sometimes. (538-587 RPM)
1. Had P0506 code but cleared and NOT returned after 2 hours run
2. Now has P1000 even after 2 hours idle/drive
3. No cel currently
4. What scanner information would you look at?
Thanks

No iac. That one should be ETC style. The p0506 is a low idle code. The truck may need to relearn the idle which is common on fords after a battery replacement. 10 mins ac off idle 2 minutes ac on. How is the condition of the plate? If it’s dirty clean it and retest it. There is a possibility it may need a throttle body aswell. It’s not an uncommon issue for a ford of that era to need a throttle body.
Don’t worry about the p1000. The ecm hasn’t finished all its drive cycle monitor checks yet.

This may give a idea. http://www.aa1car.com/library/throttle-by-wire.htm
1. I have tried relearn with no luck but will clean TB next
2. I read artice but dont see anything in it that relates other than the basic understanding of how system works but thanks for link.
