Hi everyone I have had my 99 grand prix for 5 years. It has been a good car but I have some issues. recently I had to replace my intake manifold because it had coolant in it. Has this happened to anyone else. My service engine light has been on for weeks now and i don't know why. I also lost use of my stereo when it was not running for awhile. I was told by pontiac that I would need to bring it to them to get it unlocked and it would cost me $45.00 does anyone know the unlock code

thanks for the advice, I found a couple of ideas I'm going to check out this afternoon
