my car developed a problem tonite. it idles at around 3300 "sometimes"...like whenever i clutch in it will go to 3300rpm on its own. also, the engine overheats easily...like if i go beyond 2500rpm the engine will begin to overheat. the coolant vapor is coming from the engine block and not from the rad pressure cap SO what im guessing is that the thermostat is wack isnt sending coolant to my rad at all...which would explain hte overheating and maybe the intermittent high idling.

help! i need to fix this asap.
