Weird jump at stop in neutral!?!?
I was stopped at a stop light last night and put the car in neutral and let go of the clutch. I let my foot rest on the brake waiting for the light. After about 20 seconds I felt a large jerk forward, it felt like I had let the clutch out at a dead stop in 1st gear, the car didnt die but it was very weird.
I called the dealer, I was going in to check a sticking clutch petal anyway, wonder if its connected.

yeah I'm sure, I know its weird as hell. I'm wondering if the clutch doesn't dissengage completely because of the pedal sticking problem I had. I'm taking it to the dealer but it was wierd.

If the transmission is truly in neutral, then it doesn't matter WHAT the clutch does...it is no longer a player. The pedal can stick, the clutch plate can stick to the flywheel, whatever...it doesn't matter what the clutch does, the car is NOT going to lurch forward from engine power if the trans is in neutral.

When the transmission is in neutral, the transmission input shaft is physically disconnected from the rest of the tranny. Even if the input shaft is turning, nothing else in tranny is moving or can move from engine power.
Operation of the clutch will only determine if that input shaft is turning (foot off the clutch pedal) or if the input shaft is NOT turning (clutch pedal on the floor). It has no other effect when the transmission is in neutral, so the clutch can not be the cause of this mystery.
I thought maybe by error or trans problem you had left it partially in gear. Taking your foot off the pedal might have caused the transmission to go to neutral after lurching the car forward, but it would have happened immediately, not 20 seconds later.
The guys at your dealer will thoroughly enjoy trying to duplicate the stuck clutch pedal, but they will not be able to exorcise any demons.
