I'd start by unplugging the connectors to the valve covers and looking for burnt plug and pins

Under no load, sitting in the driveway in neutral or park, does it rev up normally?

i pulled the valve covers off tested all 4 plugs that feed the glow plugs and injectors have good continuity through all of them including the cover gasket plugs im at a total loss i wonder if it could be the throttle positon sensor (i think thats what its called) or the cam position sensor

Well that's def. wrong. They should all be aprx. 1.0 ohm. Too low resistance means too high current. Still doesn't explain your performace problem. But just to be sure, have checked to see if it behaves any differently after the glow plugs cycle off?

The pedal position sensor (that's what it is, since our trucks don't have a "throttle") could be the issue. If you have access to a scanner that reads real-time data on our trucks, you can see what the sensor is feeding the PCM. There's also a manual test with a voltmeter; perhaps someone else will chime in with the procedure.
