When my truck idles it's smooth but when I get on road and the engine gets up to operating temperature it spits and sputters. When I pull into the driveway, it cuts off. I have replaced the fuel pump, fuel filter, ignition coil, ignition module and ECU. I pulled the EGR valve and cleaned it. Still no change in running conditions. Does anyone have any insight into this problem?

It will be one of important sensors. it might be RPM sensor, Cam position sensor, Throttle position sensor, Air/fuel sensor... You need to plug your truck to a right laptop which can show all the sensors how they work. Most likely it is something that causes ignition timing fault (not fuel).

Have you tried adding some heet? sometimes it fixes the most trivial things. maybe there is some water in your gas tank. our engine used to rev excessively. we added 2 bottles of heat and then it would go away. hope that helps!
