Hey guys. I am a long time lurker, but new member and wanted to hear everyone’s opinion on an issue I am having. I have 1991 #940 that I have owned for a few years now. It is 100% stock and has about 50k miles. It has run flawlessly until recently as it has developed an occasional stalling issue. It typically happens after driving for 15-20 minutes and just stalls when idling and stalls immediately upon re-starting. Letting the car sit for awhile resolves the issue. It only happens one of ten times I drive it but it has become an issue as I don’t trust it. I have searched the forum and it seems like it is an ECU issue. My local mechanic has given up so I am getting a bit desperate as I don’t have a good mechanic to help diagnose the issue. As such, I’d appreciate any thoughts on the diagnosis as well if anyone has any recommendations for a mechanic in the Phoenix area. Thanks in advance guys!!!
