engine maintaining RPM
I'm not sure how I did it but my engine in maintaining RPM for a couple seconds after I come off the throttle,
I'm using a heavily modded ARAP bin on my 305 5 speed
say I'm cruising at 2000rpm I push the clutch in and come off the throttle rpm maintains for a couple seconds
also if I don't push in the clutch in and just come off the throttle the engine doesn't slow the car down like it should it maintains speed,
its kind of like the fuel isn't stopping,
my DFCO is same all around as my stock chip,
anybody have a direction they can point in, so I can do some experimenting,
I want my engine to slow as soon as I come off the gas

It's something in the IAC control. Isn't ARAP for auto trannies? That might be causing some of your problems. I'd start with a manual tranny bin, and copy all of the known good values over to that.
