I have a 3.8l v6 2000 stock camaro with just over 100,000 miles. When running at 3000 rpms for more than a mile or two the check engine light comes on and that sounds like it's being overworked(pushed to limit). It can only run at 2000rpms to run good

 

have the computer scanned for trouble codes and let us know what comes up

 

How does it idle? At idle when you bring it up to 3k rpm does it have the same symptoms? Have you changed your air filter and PCV valve recently?

 

The check engine light doesn't stay on after dropping to 2k rpms.

If I bring it to 3k rpm idle the light doesn't come on an symptoms don't occur. My air filter(k&n) is clean and I haven't changed or checked the PCV valve. I thought it could be the fuel pump?
