03 7.3 Excursion misfire and killing problems
#16
It can be frustrating trying to nail this type of problem down as there are a number of different things that can cause the similar symptoms. Maybe we should just take them to the dealer and have them put their super duper diagnostics on them and they will have it fixed lickity split. Of course that would be cheap too.
Mine was the ICP, but it can be so many other things.
I'm just glad for all the folks here that are ready to help us work through stuff and get our trucks running right again.

Could this have something to do with a new icp sensor or do I have another problem on my hand?
Also I have a "service engine soon" light on now that I replaced the sensor, why could that be?

another way to check if it is your ICP sensor is to disconnect the sensor itself, the PCM will then default to stored tables and run off of that instead of the ICP sensor. If you have a scanner (like Auto Enginuity, Diablo Predator, the Torque Pro app, etc...) you can see the ICP change when the sensor is disconnected.
If you have a SES light after changing the ICP sensor I would bet it is most likely ICP related - were you running her hard with a chip?
Knowing what the code is would make troubleshooting so much easier. A scanner or tool like Auto Enginuity is one piece of equipment I would highly recommend for every diesel owner's tool box.

Okay so I had a buddy of mine from advanced auto run a diagnostic on the truck. first time he tried it made my truck turn off, second time it did the same thing, the third time he entered my truck manually (year, model, engine ect) it didn't kill the truck but gave me two codes..
•PO6O3 the scanner said "international control module - keep alive memory malfunction.
•PO38O the scanner said " glow plug/ heater circuit A
thats all the info I have for now. Happy Thanksgiving everyone, I'm thankful for everyone's help on this site!

Also another reason I don't run her too hard is because it has a boost leak, I'm only able to build 12psi of boost, I'm saving up to get new up pipes and intercooler boots, that should clear the leak.

Well I tried to reset the SES light but unplugging the batteries didn't do the trick.
One of the codes was for the glow plug heater circuit A, so I replaced that, that code is gone but still has the "KAM error" code.
I've looked further into it and a lot of people say that replacing the UVC harness and gaskets gets rid of that code, apparently a loose wire on one of the injectors plugs and it could send a miss, maybe that's why I have a miss in high rpms. They say this code usually comes up when the truck has a chip or programmer but all I have is a boost fooler.
I'll be looking around for a good prices UVC Harness soon and I'll post what I find out.

That's probably not a good thing... At that price it means you got aftermarket Dorman or the like and Autolite glowplugs. All of which past history has shown to cause issues. I would really suggest sticking with OEM because pulling swelled glow plugs out of the head isn't fun. This stuff is made by the lowest bidder in China and is complete junk.

They are in fact oem parts good sir, I get a pretty nice discount at my local Smyth dealer because I went to a vocational school that is sponsored by them for auto tech and body.. I do also appreciate you're input as I don't know too much about diesels. my parts dealer wouldn't lead me in the wrong direction.
