Check engine light
Pulled into our local dealer for club shop night and the engine check light came on. Checking the manual, they say it is probably realted to emissions.
Anyone else have info on this? I suppose I should make an appt. with my dealer.
Thanks!

Re: Check engine light (gmf)
You need to see what code or codes are being displayed. To see the codes follow these instructions;
Turn the key to the ON position, but don't start the engine. Clear any present messages by pressing the RESET button. Hold the OPTIONS button down, and press the FUEL button 4 times. This will get you into the CODES section of the DIC. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. Any code that ends in H is a history code (something that has occured in the past) but is fine now. Once the computer has finished going through all of it's codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# CODES".
To optionally reset the codes once in manual mode, press and hold RESET until it displays "NO CODES". Press OPTIONS to go to the next module. Repeat the steps in this paragraph until you have reset the codes in all the computer modules. NOTE !! Only reset the codes IF you want to - it is NOT necessary to do this.
Now to see what the codes mean go to this web site:

Good luck

PS: Could be something simple like the gas cao not being tight but that would be too easy.

Re: Check engine light (Buckmaster)
Buckmaster,
Headers are 6-7 months old.
here are the codes, and they were all followed with an "H".
P1518 H
U1064 H (rdcm)
I cleared the codes since they were all H
Removed the key and waited 1 minutes.
Put the key to ON and I still have the Engine Check light.
So I go through the diagnostics again and NO CODES.
What should I do next? :)
