Clutch jutter, variable engage, sticking in gear

Chris - My mech. just bled the clutch a few weeks ago when we replaced the clutch hose. He thought it might be varying due to air bubbles since the clutch hose was leaking. But that didn't fix it....unless there are still air bubbles that is.
One additional thing that seems (in my mind anyway) to point away from the input shaft is that the clutch does not hang and suddenly release. The only action that affects the clutch engagement point is pushing the pedal back in. When I do this action, I do not feel any pressure change in the pedal...the only change I feel is the point of engagement changing. I'm not pumping the pedal like I would for a brake bleed (not that I have done that in my 993, but just as an example).

Nope. It only shudders/jutters when I am releasing the clutch in reverse, and will generally keep juttering until it gains speed.
It's in the mechanic's hands for the week. So I'll report back when it's cured. Good discussion here, which always helps me de-stress about car problems. Thanks guys!!

OK, data point but not really relevant to Adrienne's problem. I had my clutch replaced and applied all of the rennlist nostrums: LWF from Viper Bob, real Mobilube SHC gear oil, new slave & hose. So I can't tell what was most wrong before but the clutch action is smooth and the trans shifts very nicely now when warmed up. Still grumpy when cold, but I think that's the nature of the beast.
The old clutch was worn but not quite down to the rivets. Input shaft wasn't dry. Slave may have been bad, it's hard to tell.
DMF was still in pretty good shape and I saved the it in case I want to go back from the LWF - my wrench really doesn't like them for driveability reasons, but so far, so good. I did a couple other while-yer-in-there things since the engine was out: PS belt ($95 for the belt!!!), SAI check valve, and the spark plugs since that way I would be positive the 12th one was actually replaced :-).
Wallet empty, car promoted to daily driver and owner happy. Good luck, Adrienne, hope yours works out too.

Best of luck on the clutch!

---UPDATE---
It's fixed: The master cylinder had a rip in the rubber booty-thingy and it was gunked up, meaning it had been leaking a bit, and certainly letting air into the hydraulics...never good. So we replaced the master cylinder, and the clutch slave cylinder while there. We bled the clutch, and now it shifts like a champ!!

Glad it is fixed Adrienne. More than likely with these cars, it was your slave that was bad and causing your issues. 99% of the 993s out there if examined you would see the boot torn on the clutch master and a slight amount of gook (technical jargon ) on the arm. It is just as well you replaced it though as they do also wear especially when the slave has not been changed.
