Big hybrid vs. smaller hybrid idle

Sorry I suck at remembering stuff, we also replaced the cam sensor due to a CPS code since he said that will change timing, it smoothed it out completely and was idling awesome for about 20 minutes until I got home and then the crappy idle came back..

It fluctuates from 580-600

Not sure about the one I pulled out but the one that went in was an International part, the grey one

The CPS code has been there for awhile, at least since I've started using a Edge CS for monitoring. I just never thought much about changing it because I was always under the impression that a bad CPS would only cause a truck to randomly stall, which mine never did. So it wasn't until a couple weeks ago that my injector builder told me a bad CPS will change timing as well, and that's when it was changed. The code hasn't been back since according to my monitor
Most of the time I have had a bad CPS it stalls and catches itself but one time it was running and idling like crap and a new CPS took care of that. How rough of an idle are we talking. Like a lope or just a little off? You said it shakes the cab?

Yeah like I said the truck idle'd really smooth once I changed the CPS, but only lasted 20 minutes or so. The oil was up to temp when it was changed, I still have the burn mark on my finger from the CPS bolt lol. So it wasn't like it had a smooth idle from cold oil. The idle is just a little off, enough that the cab shakes, or the whole truck for that matter

Just pulled the dipstick and there were a couple tiny bubbles on it..

Unplugged the ICP and found oil on the pigtail and in the sensor, started it and was smooth as glass. This was about 5 minutes ago so I'm still waiting for the oil to get hot to see if it goes back to how it normally is, but going to get a new ICP and pigtail today. The CPS code came back right after unplugging the ICP, it says camshaft position sensor circuit bank 1 or something.. Are there any other issues associated with the CPS that I could look into or is that normal when unplugging the ICP? I know just because the CPS is new doesn't mean it's good but it's a International piece so I wouldn't think it'd go bad within a couple weeks, especially considering the code just popped up when I disabled the ICP sensor

That was short-lived excitement.. Oil got to about 180 and was chopping away. I'm going to order a IPR re-seal and see what that does

The IPR seems to work how it should, truck doesn't buck or anything so I ordered a re-seal kit, also no oil in the IPR pigtail and wires seemed ok. New ICP and pigtail comes in tomorrow
