Isx15 cm2350 Low Power no codes

[GhostHauling]

2013 isx15 cm2350 demandated est 40k ago by running rough 735,000 Od overhauled at 490k truck has seemed to have intermittent power loss for a couple of months nothing crazy but last load the truck fought hard to get a 78k gross to speed on a flat hill no codes but it’s obvious now something is wrong. A couple of months ago I got one count of injector solenoid Driver cylinder 3 but truck was running fine than and code was inactive immediately after so I erased and no codes since. I pulled the valve cover and checked the injector harness no visible issues and I cleaned my imap and found an issue with my Air compressor leaking oil into the air intake so I’ve removed the compressor intake from the air intake and put a filter on it temporarily I’ll fix the compressor soon but to see if the truck would run better and cleaned all my tubing and it’s still running weak if I idle for 30 min maybe once or twice it’ll have a slight miss to it. I’m not sure what else I can besides but a over priced injector and hope that works and than continue to throw expansive parts at it. Also I just got new drive tires and a new Motive ELD device installed the Same day it started losing power oddly enough
