O2 Sensor Computer Code?????

Hey all -

I'm new to the diesel world and have problems with my 1999 F-250. The check engine light has been on and off for a few months now and I finally have been able to have it read. When it is on, the truck runs like crap, and feels like it's not running on all of it's cylinders. Sometimes it will come on and stay on, other times it will come on for a few minutes and go away and run fine.

The code that came up is P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2). Can anyone interpret this for me and tell me what I need to fix?

I originally thought the problem stemmed from the CPS recall that was not done, but since the code came up O2 sensor - I don't think that's whats wrong. Any and all help is really appreciated. Thanks!

Most likely 1316 (codes stored in the IDM )..I bet an under valve cover harness,, when its running bad ,unplug the connector to the valve covers one at a time ,,,one side wont make any difference in the way it runs ,,that is the bad side
