I have been having an intermittent issue with the 810 shutting off for no reason.Also,it would go full rich and not start on other occasions.I'm partially bald now,thanks to this issue.
A tug on one of the wires entering the ECM would make the car start.So i went thru the connectors and all related stuff.STILL would shut off.At this point the wife is vacuuming hair out of the car on a daily basis.
Then i got the idea to take the ECM apart.And i found bad solder joints.In the pics you can see
