Ok, so my engine has been idling high for a few weeks and I may have found the culprit. On the rear of the engine, a 2009 Yamaha 225, there is a small triangle box towards the top of the engine that looks like it should have 2 vacuum hoses running to it. There is one hose that runs from the IAC valve to the triangle box, and then there is another hose nipple that is vacant. Can anyone tell me if there is supposed to be a second hose running to that triangle box and if so, where does it go? Any help will be greatly appreciated! Thanks
