The Engine would stall when pulling out from a stop, but started right up again.
Sometime it would chug when going down the road. Then the service engine light
came on. That is when I had the codes read. My mechanic replaced both sensors
in less than an hour without moving the motor mount.
Without warning electrical system fails completely while driving and car rolls to a stop. Sometimes it starts again and all is well.
At last encounter it would not start in Garage. Cadillac Service Dept. sold me a new battery - the old battery was 9 months old (Bosch)
and send me on my way. 2 months later same thing happened. Took it to an Auto-Electric Shop and it was decided, it had to do with the crankshaft sensors and 2 components (out of 3) were replaced. It's running fine for now and I keep my fingers crossed.
Wonder why the Dealer couldn't diagnose this problem.
