I forgot to mention, the light on the radio stays on, where the dashboard lights go off.
Okay, if this stall problem happens again, if it was "A," what should I do to find this out (ICM)? If it is "B," what should I check for (PMC)? (see if the windows roll down? see if the light stays on? etc.)
Regarding your response, I would like to say all the above hasn't been done, but it has. When it idles in the driveway, it doesn't stall. Actually, it has been with a mechanic for one week--he has been driving it, letting is set for hours while running, etc., etc.,--and not a thing (frustration in my keystroke) has happened. I told the mechanic about your conversation with the other person about the ICM and PCM, and he said, "Yes, it is one of them. However, do you want to roll the dice or do you want me to." He said pick one and we will fix it ($400). If it stalls again, then it was the other problem." He said he can't tell me for sure what the problem is until it dies, and the test equipment registers the problem. Any suggestions? Thanks for your response.
