Have had a problem with my car for like a year now where the traction control would turn on and it would shift hard. Had gone to a bunch of good shops and no one could find out what the problem was with my car. I didn't want to go to the stealership but was pretty much ready to give in and go with them to check it out. Well when I was buying a intake camshaft solenoid at the stealerships parts dept. some guy from there referred me to another shop that he said was really good with electrical problems. I decided why not give it one more try before gm. Well they were trying to figure out what was wrong and it was something with my map sensor. The intake camshaft solenoid that I replaced only made the traction control stop from turning on randomly but it still turned on when I would step on it. Im happy that the problem is finally resolved so I can finally stop posting in this thread and put on my damn supercharger already! Just thought I'd post this for the other guys that were having the same problem and having a hard time finding the solution.

 

I'm glad to hear that this was finally resolved for you!
Enjoy the supercharger!
