From what I notice, doesn't the RPM's always drammatically drop when you take it out of gear and throw it in neutral??? All of the work that the engine was using to move the car isn't being used once you put it in neutral and you just cruise. I can't remember what exact level my RPM's go to when that happens, but I'll check it out the next time I am driving and let you know. I don't think it's the clutch though, because the clutch does the opposite when it is going, the RPM's shoot up really high with just a tap of the gas when in any gear.
