01 7.3 Rough idle no power LOTS OF CODES!!

Ok the other day I was backing up a hill and my service engine soon light came on and my truck started idling really rough and I had NO power..I got on level ground and it went away..but Now Its acting up pretty constant..I changed fuel filter and am going to replace air filter...I got it scanned and the code came up P1316,P0472,P0603,P0273,and P1295....I am soo in the dark and am really concerned because my local dealership told me that one of the codes that came up usually means the motor is shot or something seriuosely wrong internally..HELP!!!!

Did you epty the fuel water seperator. Sometimes if you dont empty the water it will contaminate fuel you said you were backing up hill which could have brought the water off the bottom.

I agree with vital: Replace both sides if you end up having to replace. I used to have a url within my favorites, of all the most popular codes that are thrown. I think there is a sticky at the dieselstop.com. That has these codes.

Look here----->Welcome to guzzle's Diagnostic Trouble Code list Web Page

You pulled the valve covers off and actually checked them? Sometimes they work themselves loose. If they are good and not comming loose you probobly should have someone with a scanner run a buzz test, contribution test for you.

I can tell you from experience that sometimes the valve cover harness will check out electrically but is actually bad. I was having similar problems but everytime I checked my harness everything was ok. I went ahead and replaced it on a hunch and luckily it fixed the problem.

Yeah to me you wiggling them to check them might have seated a wire thats when it went away and now its working itself back out. Go ahead and change the harnesses. There cheap and better to do now than once you get towed home
