Could be. Easy way to check though: throttle body/carb cleaner with the little hose ($6 tops at any auto store). Turn car on, spray around all hose openings and basically anywhere where air can get into the engine. If it idles up, you've got yourself a vacuum leak.
Check throttle cable as well. If it hasn't been adjusted to spec, that could be your issue right there. I'm not sure of the way that the engine bay is setup on the ucf10's but the throttle cable will be easily recognizable by a long twisted metal cable with a spring (more than likely) directly under or in front of it attaching to the throttle assembly (not the throttle body assembly). Should be near the throttle body though
