I have a 2007 Ford Explorer Eddy B model with 74K miles. When I drive it randomly “Jitters”. The event is difficult to describe. It happens any time; hot or cold, at start-up or after being on the road a while, when I accelerate or am at a constant speed, on cruise control or not. The only time it is not prone to happen is going up a steep incline.
The engine cuts out several times in very quick succession, or once for about 1-2 seconds. It sort of feels like a series of backfires, or that the transmission is trying to find a gear it wants to be in (as I said, this happens even on a level road at a constant speed). When the event takes place, the tach intermittentle and quickly goes from the hormal 1500 rpm (or so) to around 2500 rpm, then returns to normal.
This occurs more often lately.
There is no engine light, so putting it on a test machine is not yet an option. I have changes all the filters and uses the gas stuff to eliminate water. I let the tank get down to 50 miles of driving time and then always fill the tank.
What might be the problem?
