The list is almost endless. Get AutoEnginuity or go to a reputable diesel shop and run a diagnostic test.

At the very least take it to a shop that can hook it up to a computer. $50-$80 for a diagnosis is much cheaper than throwing parts at it. Bite the bullet and take it in.

But the shop needs to be able to read live data and know what to look for, not just scan codes and say I dunno

True but one has to start somewhere. Just asking random people on the internet is not going to solve his problem.

To the OP, look up on the Better Business Bureau and see what people have to say about shops in your area. Or if you feel you are competent enough and plan on keeping your truck around for a long time, buy the AutoEnginuity and fix it yourself. Some sensors are quite expensive and just throwing new ones on it can easily surpass the price of AE and still not have it figured out.

Here I go again up on the soap box. The 10mpg and rising prices made me lonk at how the fuel system was working and how it should work. I put a pusher pump in the back with a RSD built air fuel unit and finnished off the rest of the air and vapor issues with the pressue rise. I got all new tunes to work with the fuel system. My 8400lbs. truck gets 16.8 intown and 224 on highway. I'm a happy camper now. One more thing I had my arm twisted to do wasto run a model of the exhaust on Boing aircrafts flow bench ans my friend told me how to get the most through it.
