Hi. I have a 2006 Chev Cobalt. The car drives perfectly for about 10 to 15 minutes, then all of a sudden starts running erratically. The rpm will go to 3000 when doing 25 to 30 miles per hour. Will not go faster than 30 mph. When I use the right turn signal, a chime goes off, then quits as soon as you turn the turn signal off. Also when you mash the brakes, the shifter lockout jumps in and out clicking in what seems to be some kind of code. The lights on the front of the car also flash. After the car has been parked and cools off for a while, then it goes back to running perfectly for a few minutes. Any help would be appreciated. Thanks.

Wow, I think it's possessed.
You might have a ground problem between engine and TCM. Not sure if these problems are all related to one ground though. Have you tried pulling and re-inserting all the fuses in the underhood fuse block?
