ses light, surging and running rough

[wilbanks9]

i have a 2000 350 with the 7.3. Running around 2k rpms my truck surges like i hit the throttle gaining and losing power, then the truck starts running rough and shaking. ses light comes on and truck has very little power. after letting the truck run the light goes off and truck is normal again. any advice what could be wrong, new to diesel

From the description, I would say ICP sensor, but most of the time it doesnt get better when the engine warms up. Try unplugging it and starting the truck to see if things get better. Also could be an injector issue, need to know the codes causing the ses light for better help.

i had international scan for codes and they told me that no codes were showin up. when the truck in warm its doin the same thing. on the description that i first gave, all that is going on while im driving the truck, one min its fine the next the light and shaking and surging. when i unplug the icp sensor will i be able to drive it as normal?

The ecm uses a default (safe) value when the icp is unplugged. You can drive it, though you may be down on power slightly. But if that cures your problem, then you just need to replace the sensor.
