Have a 6.2L Iron Block Engine with GM CNC LS3 heads
Truck LY6 Intake with Edelbrock 90mm throttle body
230/240 Duration @.050
.592/.605 Lift
112 LSA
4L80E Trans with 3600 Stall converter.
NO O2's or Knock sensors

I have bee fighting this thing for a bit now, it wants to accelerate/ pick idle up when it's in gear and never wants to slow down after you start driving it stays around 2000 RPM just cruising in town.

I have tried to fight this, but either I have the issue with it idling too high in gear or the damn thing will die after a light throttle press and braking after or slower idle around town.

What’s the hot running iac steps at no load idle? Is there p/n input for gear indication?
