stalling

My car will stall randomly while i'm driving and half way on the throttle. In most cases the engine just dies. The inj duty will go to 0% and then the PIM will go to 4.98v and stay there. I can't start the car when the PIM is highlighted at 4.98v. Then for no reason the PIM goes back to normal (i.e., .98v) and i can start the car again. Any ideas?

Mine does similar but only at low speeds like downshifting from 2nd to 1st. Is yours acting similarly? Or at all random times?

it happens at low speeds generally but usually when i'm half way on the throttle maintaining a constant speed. Usually not when i'm excellerating.

someone told me it could be a failing 3 bar map sensor. I'm going to order another one through gm. I'll let you know how it turns out.

David - Check to see if your clutch switch is working, you can see it's status in the Etc, Sensor Check screen of the Commander. I have a similar problem and I think it's being caused by a faulty (or in my case not wired) clutch switch.

Thanks, I had the same problem, and that's what fixed it. $15 part
