Dam weird idle
 

Just like a lot of people here I'm new to this forum. I have a erratic Idle on my obs powerstroke, had a buzz test performed 3 weeks ago at my diesel shop and everything he said was normal, but then he called a fellow diesel mech and he said it might be the hpop?
Now I am trying to sell this truck now and dont want to put anymore money in it, and I dont like to replace anything that some one says (might) be it. Any one else have these issues and what remedy did you use. Crap it could be the o rings 229k on them, or???
5 speed
229k
intake, straight pipe exhaust, fast spool turbine, superchip
Just want it gone, it runs great but that little idle jump just irritates me, other people dont notice but I do. One last thing, when I have the defrost on it seems to have more power then it being off wtf.

Thanks

I've seen that in quite a few trucks. Your HPOP is most likely fine. Just sell it. It's a used diesel pickup with 229k miles... gonna have some quirks.
