Does anybody know where to find the service engine codes? I have done everything but go to the book store...hate that place.

I own a 02 chevy trailblazer EXT with the 4.2L. Any help would be really great. The dealership won't share info with me so I am forced to look on my own.

I am betting that someone that works at a Chevy dealership can help me out **hint-hint**

thanks
:naughty:

What code specifically are you trying to find out??

Post the codes and I can TRY to help.
