Engine Performance problem
2005 Mercury Monterey 6 cyl Front Wheel Drive Automatic 75000 miles
I had the fuel pump replaced, and gas milage dropped 3 miles per gal. Eng analizer say mixture is to rich. Mech reset fuel air mix, but the fuel mixture resets itself to a rich setting after car is restarted. I had it reset again, and drove the van 60 miles and got 25.4 MPG. I stopped, shut the engine off, restarted the engine, and retraced the same route. Gas mileage dropped to 20.4MPG. Mech does not know what to do. Help
have the same problem?
