Got the new 6.0 running about a week ago... found out I had a bad TPS and the water pump was no good, and leaking all over the place. Replaced those today, and got the TPS to work right, but the thing runs rough and I'm only showing showing 10" of vacuum out of this thing with the stock cam... Figured I'd see more, not sure if it's got a leak somewhere or what... but I don't want to install the turbo again with it like this. It'll idle on it's own but all of the sudden act like i gave it a little gas and let off, only about 50rpm difference, but it starts to hunt, then goes away, idles fine, then hunts, and back to normal... EfiLive shows nothing out of the ordinary that I can decypher. No codes or anything... would zeroing out the fuel trims cause this possibly? Any help would be appreciated. Thanks in advance guys!
