I have a 2003 ford escape 3.0 V6 and have changed the plugs, boots and springs on the coils and still have not fixed the problem, this vehicle miss fires when in park at 4000 rmp and will not accelorate past that point without cutting out and when driving it miss fires between 1600 and 1900 rpms if you step it down the pick up is fine but it is common for it to run at these rpms when driving, my next step is the throttle position senser but any help would be great as i am losing my hair very fast!
Thanx's Shawn
