2001 7.3 engine randomly missing

I have a 01 F350 with the 7.3 and I took my muffler off and it's 4 inch through I don't know if that is the problem or not. When I'm driving the check engine light comes on and it sound like its running on half power. If I shut the truck off and back on it runs fine. I have checked the valve cover connectors and shimmed them. The truck will also correct itself sometime just by letting it run. Any insight to this problem will help.


CODES
P1316
P0340
P0470

Check your warm up valve, it sounds like it's sticking.

without looking through the codes does it have a chip? could be hitting the defuel level.

What this nation needs is cleaner thoughts and dirtier fingernails...

Have an 01 F-250 and my 7.3 does the same. Idling engine light goes off and runs normal. Go down road and it comes on and runs half power and missing. Did you find your solution?
