2005 with misfire
I've been having some power loss and misfire for some time now. No cel or codes on my scangauge 2. I had a p0263 before so I replaced injector 1 checked ficm and never dips below 48.5 checked both batteries replaced glow plugs cleaned out turbo. I don't know where to look next. Maybe wiring harness? It doesn't make sense that I'm not reading any codes. No smoke no hard start just a mis and hesitation.

A few things to do and it's real easy
1. Pull and Clean EGR Valve ( don't get any Carb Cleaner in the little holes that's under the Gasket).
2. Drain water Separator.
3. Clean Map to Intake ( little hole at the Threaded Nipple gets clogged ).
4. Clean IAT2 sensor.
OOPs sorry I said a few
do you run a Fuel additive? if not you should 4oz every fill also OEM fuel and Oil Filters are a Must.

Thanks for the reply. I've cleaned the egr out and just changed the oil with motorcraft oil and filter and used rev x motor and fuel additive. I will do everything else you said and pray real hard. I've been without my truck for a few months now.

It stalled a couple times when the problem first showed. I changed the fuel filters and pump after. It goes into high idle when I have it idling in park. Also when I get up to about 50-55 it starts bucking and shaking real bad.

At the ICP connection do a wiggle test with engine running. I will post a picture of mine where it was shorting out

Btw when the problem first started I was driving to get gas at about 1/4 of a tank and it just bogged out and stalled felt to me like the fuel pump wasn't working properly so I replaced that and the filters. I cleaned the iat2 and map sensor yesterday but still running rough.
