Question about 2004 Cadillac CTS
A light is on the dash of a picture of my engine what does that mean
That is the is the check engine light, it means a failure in the emission system has occurred, take it to a Kragen or other parts store like it and they will run a test ( it is free) that will pull a code from the computer, that code will indicate the area or circuit that has a problem.
