I have a 96 F350 with the 7.3L Powerstroke. Its starting to act up and i need to get it fixed as soon as possible but i dont know where to start. When under load, or just cruising, it almost seems to backfire. It sputters for a second, then since its in gear starts right back up again and blows white for a split second. It almost seems like im out of fuel or water in my fuel but no lights light up or anything. Its a really quick buck or jerk and shakes the whole truck. Like the engine was shut off and then starts right back up within a second. Ive tried draining the fuel bowl and replacing every filter and nothing seems to help. I drive it 250 miles a day at 85mph most of the way. I keep it steady at 3000 rpm. Sometimes it just shuts off completely and i have to pull over and spend 5 minutes cranking for it to start. Is this a fuel delivery problem, or something else? Thanks in advance

 

Camshaft sensor will do that.

 

ive heard that before but i thought if that went out that the truck wouldnt run at all? is that correct?

 

Sometimes, My dad's 96 PSD was doing exactly what yours is. Research all pointed to cam sensor as being the most common cause. It fixed his. They are easy to replace and not too expensive.

 

Ok thank you very much. Got one tonight for 22.12 and going to change it tomorrow.

 

Make sure it's a real Motorcraft or International one, the aftermarket or third party sensors for this application are crap.

 

Agreeded. Alot of the aftermarket ones will will not even start when installed or will last a week
