88 Chevy pickup 305 TBI idles low and wants to stall when warm and on deceleration. Starts and accelerates great. Did decarb with seafoam. Replaced fuel filter. Plugs, wires, cap and rotor are a year old. Ran fine up until a couple months ago.

. Set idle rpm to spec.

. Replace the Ignition Control Module (ICM), if the problem persists.

I would only run ACDelco plugs in your truck.
