Running bad / check engine

All of a sudden the check engine light comes on and the engine starts to fail, like it is running on four cylinders.

WE hooked up a friends diagnostic meter the number came was up p0611 or something like that which cross referenced to the internal cam sensor. We changed the cam sensor and it was not the problem. We thought maybe it could be the injectors so we feed a lot of cleaner into the tank and had no resolve.
When we start the truck it runs rough until you give it throttle then it will slowly picks up rpm. Driving, it labors and is slow to pick up power and speed.
I have changed the fuel and air filter, changed the cam sensor and added injector cleaner.
It has 165000 miles and have never had injectors cleaned or changed. I thought it might be the fuel pump or the exhaust sensor.
I am in Baja Mexico, and will try and find a diesel mechanic.

My 97 f-350 7.3 did that and the injectors were OK but the 0-rings were bad. Replaced all 0-rings. Runs great.
