I did not know that.

A word on OnStar - I was surprised once when I called and they said the vehicle was having a code XXXX. I asked them what that code meant and they said something about idleing. Well, that was correct it was idleing bad but I didn't tell them anything about idleing. OnStar doesn't have the best customer service but there diagnostics do help out.
