P0087 railpressure too low
p0088 rail rpessure too high
you will find it under the
engine diaganotic
DTC engables about 3/4 of the way down to the bottom.. change both to "NO MIL"
or you might find the cause and fix it rather than shutting the mil off
yeah... found out... bet dirty fuel filter
Filter and Kat and Pat are sending me a nice little item to install that might help that pressure on the cp3 out some.
Note to self (from Duramax Drag Racing 101 handbook)- make sure fuel filter(s) are in good condition before heading to the track
Let me know when you get your little gadget installed and are headed to the track...Hopefully you can shave off a few tenths...
Thanks Chris, I forgot that it was the same filter I went to Smokin In the Smokies with and that it had atleast 8 different fuel stops on it, and after looking earlier your going to kill me My air cleaner is nasty as all need cleaned bad,Im heading to the metal yard in morning for tubing to make a better intake and lose my egr tube and relocate the grid heater and stuff.
