Light Engine miss in lower to mid rpm
 

So the new 02 f350 7.3 with 204k miles I bought has a slight miss to it. I can feel it sometimes at idle and sometimes not but always feel it from around 1000rpm until turbo spools up enough to mostly level it out. Running 70-75 down the hwy you can just slightly feel the un balance of it if the road is smooth enough. Since I have absolutely no blow by, I'm assuming possibly injector?

My icp is leaking oil internally and I will replace it today after work but while running if I unplug it it idles differently and check engine light comes on so I'm assuming that is not the issue?

I was told the truck just had injectors installed within the last 6 months but I have not pulled valve covers to check for myself or check to see if harnesses were replaced either.

Any ideas would be greatly epreciate. Thanks
