I have a 2006 Cadillac CTS. It is intermittently shaking when I hit 45 mph and up. It feels like it has not shifted into gear. As I said it is intermittent. I have had the alternator checked, & batter
The car has 93 K miles. It is really weird. The mechanic cannot tell me what is wrong.
He put the car on the computer and said the alternator and battery is OK. I am not
sure how to ask the questions I need to ask to get my car fixed. Something is wrong
but it is not showing on the computer. It also intermittently will not start. I have to turn
the key and put it in drive or neutral and then back to start then it so far will start. Help
so not know what to do at this point.
