I got my crab tuned pretty well i think. She idling awful close to where she should be and doesn't stumble on accel (mostly). However, when I decelerate, she goes way low in the rpms even to the point of stalling once, and that was at operating temp. After about a second or two of that lowness she returns to normal idle. Do I just need to adjust my dashpot or what?

 

Would definitely help more if we knew:
1. Year and Engine Configuration
2. Engine Mods
3. Recent changes

 

Sorry, it's a 84 S with a 12A, rebuilt nikki, emissions removed. Everything else is stock.
