I have a intermitent stalling problem on my Grand Prix. It will stall at idel or coasting at low speeds occasionally. Usually restarting right away. When it does not immeadiatly start it may take up to 15 minutes for it to resune runnig. Once this occurs everything is fine again. It never trips a code on the computer. I have replaced plug, wires and the TP sensor. Any help would be great. Thank you

Start with the free stuff.

Remove the ignition module and have it tested at any autoparts store, have it tested at least twice so as to build up heat in module to simulate heat in engine compartment.

While your there, also have charging system tested, alt. battery, starter and any "drains" on system (also free).

Have them also check for any PCM errors (even though check engine light is not on) there may be pending codes ( this is also free).

Free is good :) .
