Question rough idle

Ok runs fine pulls hard but when its warmed up and I come to a stop push in the clutch and it idles terrible and shutters all over. Sounds like it could fly apart bad enough people give strange looks. Hit the throttle and jumps to life like normal idles back down stutters like a dragster. Does not do it cold or all the time and usually if I hit the throttle a few times or let out the clutch it will stop it and idle normal any hints?

Sound like (DMF) Dual mass flywheel is going bad. Check out the sponsors links, Carolina clutch ect on this page.

Your flywheel took a dump. Mine does the exact same thing because I am too cheap to replace it yet.

I've heard that driving with a bad DMF can crack the bellhousing

Really? I figured it was hard on the bottom end being jerked around like that, but I didn't expect any immediate damage. Well, I need a new clutch as I doubt it will hold up to stage 2 injectors for very long. Amazingly the clutch itself is still in very good condition for 225,000 miles. The flywheel is all that is bad.
