The early and late CPS ( CAMP ) sensors are interchangable. If you get in a pinch either will run your truck. The difference is the metals used in the connectors. They are not compatible ( i.e. late truck with an early CPS ) and could cause corrosion over time. So if you can only find the part # that is not supposed to be for your truck, yes it will work but it should be changed out for the proper part # asap.

 

I HAVE A 99 F350 WITH 7.3 POWERSTROKE IT IDLES ROUGH ALMOST TO A STALL BUT CLEARS UP WHEN UDER POWER AFTER 20 MIN ON HWY IT STARTS TO LOOSE POWER I CHANGED THE INJECTION CONTROL MOD, GLOW PLUGS, HARNESSES, GLOW PLUG SELENIOD, AND CAM SENSOR. DID CYL CONT TEST FIRST TIME CYL 3 INJ PROB SHOWED UP RAN AGAIN CYL 3 WENT AWAY AND CYL 8 POPED UP. HIGH PRESS OIL IS AT 3000 AT IDLE AND ABOUT 14000 RACED UP AND DID OHM CHECK ON INJ ALL AROUND 2.8 GONNA PULL THE REST OF MY HAIR OUT WITH THIS TRUCK SOON

 

Skybuster83, you might want to post this as a new thread rather than tack it on to a 6 year old one. Also, on the net all caps is like shouting. With that said, welcome to FTE and the 99-03 7.3 psd forum. The guys here are much smarter than me on this stuff and will help you out.

To post a new thread go to the 99-03 7.3 forum page and open the new thread at the"new thread" like.

 

I don't know if this is the correct part # for our trucks, but here is a ford one for $23.

oh how the times have changed!!

 

Sorry to hear about the trouble, you will be able to fix it here if we can get answers to the questions you'll be asked. I'll start.

* Describe the "rough idle" (ie. when first started, after driving, how about outside temp does that make a difference)
* How many miles are on the truck, any mods on it, has the maintenance been kept up?
* Why did you replace the Injector Driver Module (IDM) (that is what you meant by the Injection Control Mod right, behind the driverside fender)
* Can you tell us more about the "harness" you replaced? (which one, why)
* Do you have the ability to do contribution testing, or did a buddy/shop do it for you?
* Could you confirm your PSI readings for you High Pressure Oil Pump (HPOP)? 3000psi is about all your HPOP should be able to deliver, stock. 14,000psi would certainly dictate the next GTG to be at your place J/K
* How much fuel is in your tank?

Please don't take all the questions the wrong way, sometimes not only does it help to know exactly what you did, but why it was done. It's more challenging to diagnose mechanical problems over the net, but this site is probably one of the best for success.

My initial conclusion would be:
1- Could be a clogged fuel filter.

2-Your Injection Control Pressure (ICP) sensor, especially if your psi readings were in fact what the scanner read. Try disconnecting this sensor and inspecting the contact area, is there oil in the plug? Also, what type oil are you running, and what is its age/condition, this can play a role in how the truck runs... if it is dirty, or has run dirty oil, debris could get trapped in the Injector Pressure Regulator (IPR) and cause erratic engine operation.

3- Weak/failing fuel pump

Just some things to start with, my focus would be on the psi readings though, your numbers are way out of OEM specs, and Welcome...

 

Idm was changed cause when suffolk county brake did the cyl cont test it kept on changing injector that was malfunctioning. i changed the oil about 2000 miles ago i change it every 5000 with rotella t i canged the fuel filter as soon as i started having the prob. the harness that i changed was the valve cover harnesses. it is my uncle that did all the testing he is the head mech over there he had 3 ford tech come to try and diagnose it and they spent 2 days working on it and couldnt figure it out. he said hpop 3000 at idle and 14000 when raced up i was there when he tested that and i saw the numbers. the truck has 79000 miles on it, fuel tank has about 3/4, and rough idle is at all time and any outside temp and no mods to truck all stock

 

ICP sensor have any oil inside the plug?

 

So Dan, think the ICP may be giving those HPOP ###'s? They seem consistent, maybe a resistor in there from the PO?
