Man I'd love to hook my scantool to your car.... I'm intrigued... On the same note I have heard of people having issues with a ground( several wires ) thats under the drivers side carpet if memory serves... Don't quote me on that.... You could be having a computer issue asa well... Hard to say without being there... Good Luck..

Been there, done that! Last year I had that repaired, The driver'* door seal had been leaking causing a ground failure. That actually caused my car to just quit anywhere, anytime, It took the Tech awhile to find that! I think you may be right in that a ground could be a possibility. I just dread the thought of finding where it could be. If I can wrangle up an ECM, I'll replace it just for grins. I WILL eventually replace every component on the entire car. I REFUSE to drive any lesser of a car!!

Bonne'* Rule!! My 1st was a '66 Brougham White/Black All options including: (reverb, rear defrost, power antenna) Dreamin'...........

Default 95 ssei stalling when hot

I am having an issue with my car for the past year or so. I drive it for approx. 30 minutes, the car is then hot. I ll stop and go in for about 10 minutes and come back out to start her up and go somewhere else. When i start it up my car stalls,clicks, many noises, but no check engine light? Its become a problem now beacuse my car will actually die right out, this is new it never did this in the beginning. I got about 155,000km on her, with a cold air intake, 2.5'pulley, catback 2.5" exhuast. This problem occured before all of the mods. WHen it begins to stall out the air around my car gets very rich smellling of gas, its not bad gas i always use 94octane? What can this be? Can somebody help my car out? I read a few posts about a high flow cat, we have that emmision testing in Onatrio canada, and im afriad my car may fail so a new cat is on the list( rattles inside the cat) Thanks hope to here back with all of everyones suggestions, or if somebody has had a similar problem.

Well, still sounds like a bad fuel pressure regulator.

I had a situation where the car would start and run fine until it got warmed up. Then it would idle rough and stumble. It would do this while driving as well. Sometimes it would get better. It turns out it was the EGR valve. I don't know if this is your problem, but I thought I give you my experience.
