Finally, maybe progress: Code 0470.....
Been have intermittant problems: 1)Either the truck misses at idle or 2)the truck idles fine but runs with low MPG/Power, or 3)no problems at all. Finally it throw a code 0470 Exhaust Back Pressure Sensor Circuit Error. At this point, being new to things mechanical/PSD, I need some direction.
Thx's, Fred ( jyblood@nwi.net ).

Here's a link on how to clean the tube mentioned Welcome to guzzle's Exhaust Backpressure Sensor Cleaning Maintenance Web Page
When it's cold outside and the engine is cold, will the truck increase idle on it's own after a minute or so?

I was getting the same code followed the link they gave you on this thread. I only took my sensor off and cleaned it really good and made sure I got all of the black build up out of the bottom side of the sensor and put it back together. I got lucky and the 470 code is gone. the link is really helpful when followed step by step. Good luck!!

Good job, makes these hours spent here worth it when someone fixes it.
