1994 Ford Explorer Eddie Bauer 4.0L Poor Idle Quality
Posted to Ford Driveability on 8/9/2001 4 Replies

i thought i had this one fixed by changing the mass air flow sensor, i worked good for a couple of hours. the problem is very intermitant, i will go into a rough idle and when driving will act like running on 3 cylinders and then come out of it and drive fine....
