Idle Learn

[Jeff Flanary]

Thanks, The reason i asked is i have had the 747 out and changed the prom in
it.  It runs fine, but every now and then, the idle will go up & down, when
sitting in traffic.  It has been a couple of weeks since the prom change,
but the truck is driven very little, mainly, just a little on the weekend,
so maybe it hasn't been driven enough yet.  It did the same thing with
another 747 and a different Prom year or two ago when i had went from the
later model TBI ecm which was i think ????16136965????? to the 1227747.
Thanks again, Jeff.
