Why is your check engine light still on if you already cleaned the EGR valve and the vacuum works?

The "Check Engine" light is a diagnostic indicator showing that the On Board Diagnostic computer has detected a problem and has saved the trouble code. You can get the trouble code from the OBD system using a special computer attachment. Most auto parts stores will get the trouble code for you for free (and be happy to sell you the part that would need to be replaced.) Check the trouble code to insure that it is referring to a flow issue. If the electrical system is At Fault, consult your service manual for the proper test.
