Hi, my 2004 ford Taurus
has check engine
light that says both banks running lean. The mass air flow sensor was replaced, but this still didn't fix the problem. Usually at least once a day, the engine revs while driving and I have to drive while using the brake
rather than the gas pedal. Are these problems related?
JA: Does the light stay on solid or does it flicker? Any noticeable performance problems lately?
Customer: The light stays on. No other problems other than the engine revving, and will occasionally stall while driving very slowly through playgroung zones.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: The school mechanics teacher where I work has tried replacing the mass air flow sensor. He is thinking of replacing the lower manifold intake gasket. I was just looking for a second opinion.
JA: Anything else you think the mechanic should know?
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.
