Default WTF!!!!!! TCS turns on and off by it self! HELP!

just like it says, my TCS switch turns on and off by it self. The switch does not work. Any body had this problem before and knows what is wrong? It is very annoying when you can't turn it off when you need it to.

You might have a vaccum leak since your running a 224 cam, I don't think I had the same problem you do.

Have you tried checking all you fuses also?

Default Tcs

We have the same problem on a customers car. The TCS would come on and the car would not idle. When you turned the TCS off, the car would instantly come to an idle. We never found the problem that is still causing this...

I had this problem on my Z......check the little rubber hose about 1.5" long right behind the throttle body that connects the PCV hose to the side of the intake manifold......it is very soft rubber and I had a hole in mine. It took a long time for me to ever throw a lean code, but I had an occasional ASR on then off by itself and a very rough idle. Sometimes I would start it and it would idle at about 1500, shut it off......start it, and it would idle normal......very strange.
