HI
We have a Hellcat Engine - transplanted into an old classic Studebaker
All runs perfectly - except when warm (and only when warm) it will often when coming to idle at the lights - start to hunt - cycling between 400 and 900rpm and after a few seconds stall.
If put into Neutral before coming to a stop its fine - but if in DRIVE will usually stop.
Mixtures seem fine - and the Throttlebody has been replaced to try to find the issue - but to no avail.
Tune is standard
Can do a LOG FILE if that will help
Any ideas and suggestions will be appreciated
Thanks
