Rough Idle, Falls On face sometimes after clutch is depressed

My truck will sometimes idle wierd, what it will do is idle fine for a while then every now and then it will kinda jump just a little bit not much maybe 50 or so RPM just bearly noticable on the Tach and when it does this it almost seems like it runs better. Also sometimes when i depress the clutch fast the motor will kinda fall on its face, it wont stall, just kinda struggle for a little bit then come back out of it after a couple seconds.
So far i have a new 17* HPOP and IPR
also new CPS

Im starting to think i have a faulty injector, but i did a Contribution Test a while back and everything passed, got two codes from it though P0196 and P0236

Truck will be outa commision till Prolly this weekend, Dual Mass Clutch finally went, ill be tearing it down tonight and tomorrow, then friday new South Bend Clutch should be in. I would still like to get these last few kinks worked out though, it those little things that are hard to find that just drive you nuts

thanks

You will probably find that the problem is gone when your new clutch is in. Sounds like a classic problem with the stock dual mass.

replaced the dual mass with south bend solid con-o both problems are still there, think maybe it is a faulty injector?
