Stumped...

I have a 99.5 7.3L and it runs rough on start up with the check engine light on. It all goes away when the truck warms up. I just replaced the CPS and all it did was go away for a few minutes then come right back. I cant get it to read any codes, and I am reluctant to take it to my local ford dealer because they always give me the run around. What do I do next?

Take it to a diesel repair shop. Let them use there high dollar equipment to get codes for you. Unless you have a program like auto enginuity or a highdollar scanner you most likely will not get any codes. Being the cel is going off on its own. It would be considered a soft code. Most code scanners will not read these or detect them.

I could speculate that it is a fuel problem, or injector problem. Which when the engine is warm goes away.

sounds like under valve cover wiring , possibly , if you dont want to take it in may want to remove valve covers and look, but it still should have set a code in memory

I have an update. I changed the CPS and now the CEL doesnt come on intill about 2 minutes after its running, but it now longer goes off when truck warms up, but it will go off for a few minutes then come back on... Maybe I will just have ford run the scanner and see what codes it is giving. unless anyone knows a good diesel shop in the cleveland, oh area

If you have to take it to a shop, I don't know any performance ones, but they have a good tech at Mike Bass Ford in Lorain- I ended up getting towed there when my IPR went out and they were good to me... not cheap though, but good guys... almost had a PDA with plug and software- but I was nice and took it back in to them before I left...
The guys up front are the commercial truck service garage- they do the PSDs, the back is the car dealers- they are clueless...

Before you spend money, did you try removing the Juice? Seems like you'd want to try the free thing first...

Why would the edge cause problems now, when I have been running it for months? or does the edge just suck. I have had it set on 0 which is stock and no difference.
