jerks while cruising
Hello All,
I hope someone can diagnose my problem.
I have an 87 f150 with 5.0 and auto trans.
Here is my problem:
When driving at highway speeds, maybe 50-75 mph all of a sudden my truck jerks real hard as if it is tied to a tree with a rope and when I get to the end of the rope it jerks really hard and then breaks the rope and I can go on down the road with no problem.
It might jerk again in 5 minutes or an hour or might not do it again for days, maybe even a week or two but it will do it again.
This scares the hell out of me every time it happens and I am gettin' tired of gettin' scared.
Any ideas?
Also I have a trouble code that says MAP sensor is out of range.
Can it be brought back into range or do I need to replace the sensor?
Thanks and keep on truckin"

What I'd do at this point is check the wiring and connections between the MAP sensor and computer and check for vacuum leaks. Then disconnect the battery for 15 minutes or so to clear the computer. If the code comes back, then replace the MAP sensor. Also, how long since the fuel filter was replaced?
