Hey all, this is my first post as you can see!
I just bought a 1996 f250 7.3 and it's been giving me 3 different issues.

1. When I first start the truck, it surges and jumps up and down about 3-10 times, then stops and runs fine.
2. Then when I'm driving it around it suddenly loses power out of nowhere, but just for a second, and usually doesn't die.
3. Twice now I've been driving around and the truck will just completely bog out. I'll have barely enough power to keep the engine running, and drag myself home. It will rev up extremely slow.

I replaced the fuel pump, and fuel filter yesterday and still has all the same problems. Although I haven't been able to replicate problem number 3 yet, because I haven't driven it around enough, and it happens pretty rarely, so who knows if that helped or not.

I have a few ideas of what it mights be, but they're all expensive items to buy if guessing, and a more educated guess would be helpful.

Could maybe be HPOP, CPS, MAF, IPR, ICP, or UVCH?

Thanks in advance!

 

UVCH mad pig tails will be my first guess, unplug the ICP and see if there's oil in there as this an affect how the truck runs, if there's oil in the oil connector cmreplaxe with a MC or IH part only.
And welcome aboard to the best forum around IMO.

 

Thank you!
Okay, I'll go look at the ICP.
If there was a UVCH problem, would it not should up in the engine codes?
There is no check engine light on.

 

when I removed my UVCH connector while running, no CEL came on

 

Yes it's possible, when there's melted pins shorting out, the IDM will shut the problem bank down and give the symptoms you are describing. Good luck hopefully it's something as simple as loose connector.

Have to ask, what does this mean ... Gicduhdthhv ... saw it on your other post too, thanks

 

It means nothing haha. I wrote something, and it wouldn't let me delete it

 

OK, I think once you get some more posts you can see the EDIT button, not sure, and can change things, just never saw the same phrase twice on different threads. Just curious ...

I have the exact same problem. I just got mine back from having the problem checked out and the mechanic unplugged the High pressure Oil censor and cleaned connectors and plugged back in. He wasn't able to replicate the problem I was having so we figured loose connector.

I will be replacing that censor. I was also told that it would be a good idea to replace the cam shaft censor as well.
