2002 F-350, 7.3L Cam Sensor didnt fix problem

My truck keeps dying. Originally, it would just die going down the road but would start right back up, most of the time. I changed the cam sensor and it stopped doing it as long as I kept the truck around 2000-2500 RPMs. If I go over that, it dies but starts right back up. Engine Light and Water in Fuel lights come on but go away once started. Changed fuel filter, still doing it. On to my second cam sensor already. Runs great as long as I am not running up a steep incline and if I keep it around 70-75 mph. If the turbo kicks in going uphill which is usually around 2500-3000 rpms it dies and then restarts. If I try to pass someone and kick in the turbo, it dies and then restarts and will then accelerate. Dealership shows no codes and recommended the Exhaust Back Pressure Sensor? Any clearer direction to take or is that it?

You could get a sensor delete thing from blackclouddiesel.com and see if that works.

Is that exhaust back pressure sensor easy to change out? I have been looking online for some easy directions but cant seem to find anything. I think because it isnt doing it all of the time, it wont throw a code. Can you drive around with a diagnostic unit in your truck so when it does die it will read the code?

yes u can just be sure to unplug it when the truck is shut down for a while or ur battery will go dead. that sensor is locaed on the front of the motor rith next to the water pump. look on the exhaust manifold up on the front at the top for a fitting with a metal tube connected to it follow it to the sensor. the sensor is mounted to the bracket for the HPOP gear bolt cover, right ont he front of the motor in the middle.
