7.3 givin me troubles

[workin4my350]

Guys, I know I dont post much, just when I have Issues.

Soo here is todays.

driving down my road. truck was doing good, then all of a sudden . the rpms dropped, the truck hessitated ALOT, the engine light came on, and then it would bearly make it up a little hill.

I pulled over, checked the oil. The oil is a little low (at the bottom line). Felt for metal chips, etc. Had a little sparkly look to it (maybe small chips), and some bubbles to the black oil.

What might be the trouble.

Sounded like a pinto not a 7.3.

I had tranny trouble a couple months ago,and went to tranny shop. Got a 1-2 tranny code, had a kink in both tranny cooler hard lines. I got that fixed (many hours of hair pulling), and got a complete flush, with additive. two days later it started slipping. May need that now. So, what do you guys think.

Im leaving to go out of town next week, so might have to hold off on the truck, but need advice.

BAD.

thanks,

Bill

CPS, uvch, oil bubbly might leave air in the hpop which may not fire the injectors...

You need to check the oil more often on these trucks, I never let it get bellow half of where it reads.

The 2 most common problems for our trucks IMO are CPS and valve cover harness. I'm not positive but I think you changed your CPS not to long ago, correct? Our trucks have the injector wiring harness going through the valve cover gasket. It is not uncommon for them to deteriorate and cause the problem you listed.

Under valve cover harness is the first part I ordered for my truck, then the CPS.

I did the CPS last year. Is there a tech article on the valve cover harness?

Thanks for the help guys. Really want to keep the truck, just need reliable trailer hauler.

I don't think there is. It's really easy just a little time consuming. If you can take off the valve covers and plug a couple things in then you can do this also

got it.

thanks

Check the passenger side first. For whatever reason this side seems to go first. Both times on my truck it was passenger side.
It is straight forward as far as removing the valve covers. If they are fried it will be obvious, fried wires and burnt electrical smell. I got my replacement harness from International.
