If your RPM's go crazy, it's the transmission. It sounds like you may have a leak in your radiator- either the radiator leaking into the transmission or vice versa. This could leave you stranded on the side of the road if you don't get it in soon, and cause irreversible damage to the transmission. It COULD be the fuel pump or the spark plugs if its not the transmission/radiator. Best advice: get it to the shop ASAP.
