I brought my 01 Civic to the Honduah Stearship earlier today with a problem with vibration (turned out to be a broken engine mount) and irregular rpms.

when i would start the car and the engine was cold, i would rev anywhere as high as 1300 rpm for up to 5 minutes. after it cooled, it would go as low as 600 and sound like it was gonna stall. the guy at honda said i need my load controller replaced, however when i asked him what it does, he couldnt give me a square answer. has anyone heard of this part? i just wanna make sure im not gettin sold a muffler bearing or anything like that
