background for the last 3 years (80,000) miles after a long trip (over 100 miles) when I would stop at a stop light getting off the highway and at all stops until truck sat for a while it would run real rough.
also missing and sluggish on take off up to about 2000 rpm than was fine
short trips no problem! daily driving no problem!
oil changed every 5,000 miles, rotella synthetic since new.
I finally found the problem.
any one want to guess?

 

Loose IPR nut.... I wanna know, cuz mine does it sometimes too.

 

im guessing it has something to do with fuel. maybe your injector pump was going bad or ur hpop.

 

Oil issue, foaming?

 

I will try fuel tank vent issue.

Bill

 

I'll try hot turbo by restricted air filter.

 

found that laying in the valley with about 1/4 inch of build up on it re installed no change

haven't changed any pump.
always the same with new or old oil, with or with out additives

nope not tank related
been through many filters, started with the factory filter still did it with the 6637

 

Mine does it too..when you tap the brake and the tc frees up, it runs like it has a huge load on it and it wants to shut off...idles real low then comes back up. I barely use my brakes at stops just to get around it. let me know what you find. Whats an IPR? And how do you tighten the nut?

 

mine is a 5 speed so not torque converter or TRS related

 

Carbon build up in the EBPV sensor tube off the passenger side exhaust manifold?

 

Something oil related ?.

 

bad icp sensor? god danget man just tell us!! lol

 

cps maybe?

 

spit it out. iam about to go on a long trip this week, i wanna know if i need to do somethig before i leave

 

EOT sensor.
