If your rpm's are going up without the car "moving out" then I'd say the clutch/pressure plate. Generally you can hear the engine "rev" without a doubt.

Park some place its safe and put on the parking brake and try to take off. Listen for the engine to rev and you not going anywhere.
If its the clutch it may be as simple as adjusting it some?

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
