I have new moose buddy injectors installed and corrected timing since i installed them with a very nice increase in the seat of the pants feel my idle is still a little lumpy. Is this normal? Its not as bad as the old injectors but its still very noticeable. It seems very smooth when cold after high idle kicks off but it doesnt take long to start loosing its smoothness. If this is acceptable il write it off and not worry i just want to know. There cdi injectors so they have been matched in pressure as far as i know.

Not today im out of town.

Im referencing visually the truck shakes slightly side to side at idle. The shifter handle moves side to side.
You cant tell by looking at the truck while its running but sitting in the seat you can feel the slight movment like a gas motor with a slight miss at idle.

It's possible that your flywheel is going bad, assuming that you still have a DMF.

Idle might be too low? What rpm are you idling at. When I put my new injection system on my 6.9, it idled at like 625rpms.. I turned it up to 700 and it was pretty smooth 750 was perfect.
