Engine Mechanical problem
1999 Ford F250 V8 Four Wheel Drive Automatic 381300 miles
While driving the engine trys to shut down and bucks.
Sometimes the check engine light comes on but will not leave a code and when you shut off the truck and restart it the check engine light goes off. It seems to be worst when it is raining or damp out. I have changed the cam sensor and it still does the same thing. I have put diesel treatment in the fuel changed the filter and it does not seem to help.
