Answer
Hi Tim,
If it is a 2000, there is no way for you to adjust that.
You can make sure there is a clean air filter, the engine is tuned properly, and any if the engine light is on, read and correct any codes.
The ECM,(Computer), uses input from sensors, and changes the fuel mixture accordingly, and constantly.
Bad sensors will cause an improper mix, but should illuminate the check engine light.

Some injector cleaner run through the gas tank might help.
