Thread: Sudden problem, truck dies at idle and some black smoke from the exhaust

It will be interesting to see if your stalling out problem is just burned wire boots. Sounds more like a carb issue to me, like maybe a bad vacuum idle pulloff valve, or a bad idle solenoid that kicks in with the AC? You mentioned driving a lot on 100+ days with the AC blasting. Let us know what you find when you change out the wires & plugs.

Kinda what i was thinking too, like plug wires etc are part of the problem and the carb is doing something stupid too like dribbling raw fuel into the engine.
