They ended up buying the car back. But before that they kept saying nothing was wrong with the care. Besides the bad computer, it also had a bad throttle position sensor. I had to do all of the testing myself to find out the issues before it took them a year to buy it back.

I have the same problem, could you help me? thank you

[@Last8501]

That is limp home mode on the car. Look at getting a new computer. That is what I was finally told, but GM bought the car back before the computer was replaced.

[@jbarojas7]

@@Last8501 So I need to replace the computer.

[@Last8501]

It depends. At the time a new computer was$200 but GM refused to replace it. If your car is always doing it, they should be able to tell you why it’s doing that. If they don’t know, try having them replace it.

I was just driving mine on the high way all off sudden the car was gutless barwly any throttle check engine light came on checked all fluids antifreeze seemed low any ideas?

[@Last8501]

Tha Professor if you can pull the codes, see if it is the throttle position sensor code. If it is, replace it. That was one of the issues we figured out.
