Depending what you have it's probably the one for injectors to straighten it up on cold starts..it works, just remember to uninstall your flash mods (programs) if you have any.

I don't have anythig in the computer that I have installed but the truck skips and runs ragged #1 cylinder is not working I did a continunity test on the harness and that checked out just fine I am certain it's something in the elecrtronics and was told to take it to the dealer to have it flashed . I guess it's more than disconecting the batteries ?

I don't have a scanner to test it with so I don't know The check enging light comes on . The electronics make a diesel engine operation so dificult . Any mechanical one is so simple but this one has me stumped .

Yeah you have codes stored if the ses light has come on. Depending on codes you may have to do a injector buzz test and depending on that test possibly a cylinder contribution test. Find a way to scan it! Its a good place to start your troubleshooting, so your not throwing parts you dont need at it:thumb:

Yes I know what you mean I took it to one place and after $3100.00 and replacing parts I didn't need I am a little cautious where to takle it now .. I hate it when they keep throwing parts at it . I want it checked so I don't spend money on parts I don't need . I live in an area where I am limited where I can take it so I think after all I been through the dealer may be my best choice and instruct then thay I want the problem diagnosed only . At least I now have a better idea what to ask for .
