having a little miss

Ok guys this is my first post on here and received alot of help from reading some of the other post. But I am a little confused where to start with this issue. My truck is a 99 and has over 250000 miles on it. It is a daily driver with the occasional weekend camping trip. Just put a used turbo on (out of town when I started to lose the old one and had to get back home with a camper and family) and new injector cups and glow plugs and relay a few months back. Now it seems to have a miss in it now. I have read that I could be losing fuel pressure and maybe injectors are bad and ICPs and different things. The truck seems to have a constant miss. It seems that the weather does not have any change in it. Where do I need to start Thanks

Low, bad, wrong, old oil can cause missing.

when you replaced the injector cups did you use new injector orings and did you oil them before they were put back in the truck? if not it could have damaged one or more of the orings.

Also, at that mileage, unplug the ICP sensor and see if there is oil in the connector.

They did get some oil I would not say a alot of oil. And maybe I gave a bad description earlier but the truck runs fine it is just when idling that is seems to have a miss in it.

Thanks Shawn. During the day I post from my phone and linking threads is impossible.

If it is just a miss at idle, you are probably just getting the effects of #8 being at a dead end. Check out the FRx from Riffraff. I would post a link but.... stupid phone
