We took the Cadillac to our usual mechanic. He had left a ground wire off of the computer (in the trunk) when he had installed the struts. He put it back, but the problem with the car shutting off is still there.
We now have the car at another shop. The mechanic (owner) is an "auto electrical specialst". I spoke to him today. He admits he is stumped.
He said he "ran all the codes" but nothing in the code history indicated a problem. Basically, no codes are coming up.
He said he went to the "cadillac" site and checked for "bulletins" but nothing was posted.
He said, Chryslers used to have this problem of shutting off, (1992s). The computers would have to "re-learn" the firing pathways (or something like that), but this was usually solved by driving the car one time.
I asked him, could it be the battery. I forgot to tell you the last thing I did was put a new battery in the car. The one before that was only 2 months old and was bad! He said, no, it couldn't be the battery, or the battery cable.
I asked him if it could be the car's computer. He said, no, because if it was, the car wouldn't start up again right away.
I asked him if it could be plugs or wires (tune up). He said no, he thought that looked good.
I'm just updating you... I need to take your suggestions to him because now that I review them, I see we hadn't discussed some of these points with him. In the mean time, if you have any more ideas, please let us know.
