I had to jump in an 06 T800 and back a couple trailers into the dock the other day. At certain points I couldn't hardly see anything in the mirrors because they were vibrating so bad. Been so long since I've sit in a KW I forgot about this issue.... Anyway to get to my point, is there any way to solve this, besides like slipping the clutch, and revving it up a few rpms?? Is something loose or what the heck??
I purchased a w900 just over a year ago and have this issue, just an extra 50 rpm's takes care of it and it stops, next time my ecm is looked at i am going to ask them to boost the idle up.
You might have already tried this, but on a lot of them you can change the idle speed by turning off the cruise switch then use the set / resume button to change it in 10 rpm increments. It will stay that way till from then on.
I heard ya'll were discussing vibrators in here. I gotta tell ya about...oops, never mind - found my glasses...
Really nobody else has ever had this problem?? Every KW I've ever been in has done this......man I don't see how you can put up with this. Major PITA if ya ask me, glad I'm not stuck in one of these trucks daily!!
