Sounds like an ECU issue.  check your fuses, see if you can get an error code from a scanner, they have one at most checker auto stores that you can use for free.  Could be a Intake Air Temp sensor or a Throttle Position Sensor.  Thats what I would start with.  Good luck.

You probably have an air leak in the fuel line. Air bubbles rise to the top-most area of the tubing and form a "vapor lock" . Find the leak, stop the problem! IT's probably a loose connection somewhere.

Injectors are going bad. Might try fuel additives and changing engine oil to see if they might get better.

I have an 1996 f250 powerstroke and it is running rough.


The most common problem is a bad fuel injector but if you haven't already done so--check to make sure your oil level is all the way up to full.Power Strokes use a high pressure oil pump to operate their injectors and if your oil is at a low level it can cause air pockets in the lines going to the injectors.It's not a real common problem but I 've seen it happen maybe 10 times.Another cause is using the wrong kind of oil.Some oils have a tendency to foam at high pressures and can produce air in those same injector supply lines. Good luck!

I had a problem with vacuum in my F250 diesel. It had a new vacuum pump but would kick out of cruise control every time the vacuum pressure dropped. It turned out to be the vacuum reserve cannister had holes in it.

Seems you reach a tipping point and then all the vacuum systems mess up. You might want to check the reserve cannister and any vacuum servo your 4x4 might have. You can check most of the vacuum stuff with the engine OFF using a vacuum pump. You could have a leaking vacuum pot operating the ductwork. Check your diesel vacuum pump for output and loose belts.
