Engine Performance problem
2002 Mercury Cougar 6 cyl Two Wheel Drive Automatic
I have a 2002 mercury I have replaced the egr value, the egr control solenoid, hoses are clean. Yet the check engine light still comes on I had the codes checked and it still says egr valve flow. Please help I need my car to pass emmission.
What was the trouble code you received? (P0100, etc.) This will help us better assist you with the problem.

The code is p104

P0104 indicates a fault with the mass air flow (MAF) circuit, not the EGR circuit. You will need to inspect for leaks in the intake system, faulty wiring to the MAF sensor or a faulty MAF sensor itself.
