Not sure what rough and grabby is in this situation. Do you mean the engagement is grabby? Or the peddle itself doesn't release back smoothly? Is it grabbing on the floor mat?
The pedal travel doesn't feel smooth. I'm fairly sure it's not grabbing on the mat but I'll remove the mat and check.
If I feel the same roughness in the travel with the engine off, that should eliminate the clutch disc and associated bits as the source of the problem, yes? No?
