Why would the antilock brake light come on?
Antilock Brake Light comes on and stays on when the ABS computer detects some problem with the antilock brakesystem components. You will still have normal brake use, but the Antilock system will probably not work as an Antilock brake system is supposed to work. ABS system diagnostic code readers are available and are recommended for diagnostic purposes, however fixing ABS systems is perhaps best left up to the Pros. . .
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.
