Runs Rough after Top End Work
05 F350 King Ranch Crew Cab 6.0, 265,000 miles. Head studs, EGR delete, Atlas 40 FICM tune by Ficmrepair.com.
Head studs and delete were done st 160k+/- miles, did not do oil cooler at the time. Went hunting in September, truck ran hot pulling a trailer, 225+. Deltas exceeded 20 degrees. Got to camp, truck did not start . Though HP oil leak. Waited till the oil cooled down and ran fine. Got home and applied air. HP leak on passenger side. Decided to change the oil cooler at the same time. I Had it tore down a ways this time. Could not afford new injectors, but noticed #3 had a bad o ring. Decided to take all 8 in for new o rings. Put it all back together very carefully, obeyed all torque specs, no leftover bolts, etc. Filled filter housing with over a gallon of full synthetic Rotella. After a bit of cranking, it started. Ran rough at idle, so decided to put some miles on it. 35 miles later still running rough. Scan gauge says FICM is fine, IPR varied 14 to 35 ish, exceeded 87 when I first started it. Not sure what's going on. Any ideas where to start?

I would agree to pull the IPR to clean the screen, but that's not why it's running rough, running rough due to injector issues... do a bubble test right after you pull the codes. You probably have a bad injector.
