It comes on when my car is idling and goes away when I rev up the engine....... And sometimes the engine has problems idling..... Any ideas?
 
Many ideas... I'd start by pulling codes.

In no particular order..

Fuel Pressure regulator. - Pull the vacume line off it and make sure there is no fuel in there.

IAC - Idle Air Control could be failing

Air leak in the intake system. Should cause an increase idle speed, not slow idle.

There are others
 
It's mounted to the fuel rail. Round valve with a vaccum line attached to the top. Look for the chromed fuel rail and follow it until you find the regulator
