ya still under warrranty, 100,000 powertrain

 

take it to another dealer, there could be a leak somewhere in the fuel supply lines going to the cp3 and its drawing in air, is the bleed screw on the fuel filter tight? as tight as can get it with you fingers should be good enough

 

ya it is n i got a service scheduled with some cross town competition...how long would you say it should have taken to get all air out of lines from changing the filter and then bleeding it on saturday

 

you can use the hand pump on top of the fuel filter housing to pump post of the air out it takes about a million pumps but fuel should star comming out thhe bleed screw once its ready, the cp3 works under a vacuum so it draws it own fuel, if theirs a small hole in the fuel lines somewhere itl suck in air and cause the engine to run like crap.

but there could be something else wrong with it. but that's where i would check first if i didn't have a warranty

 

i might be nuts but it seems like it likes to do it more to on rough roads or if i swerve or somethin??? maybe???...new ECM new filter new diesel with diesel kleen cant be much more than a bare wire on the harness a bad fprv or a line leak

 

a bad fprv is easy to diagnose using a bottle test. you can try that and see if that.

is your tank full?

 

just topped it off bout an hour ago

 

hmm, might try another dealer then

 

no not now i got it now but hey want it they wanna find somethin to screw me over on with it cuz "my old man and i are the only ones that have these duramax problems" bullshit they just aint got a mechanic that knows anything

ya but ill look over the lines and such because an air leak would be high on my liat however a wiring problem is crossin my mind too

 

check the injectors harnesses, like #7 back passenger side see if it loose
