What causes a snowmobile to idle high?

Why is the idle speed of my car so high?

Step 2 – The idle air control motor (valve) is responsible for controlling the engine idle speed, if this part fails or becomes weak the engine idle speed could become erratic, additionally, this condition may or may not trigger the MIL (check engine, service engine soon light.)

How can I keep my car at idle?

Step 3 – Engine vacuum is a sealed system and must hold a specific amount to maintain proper idle conditions, inspect the engine vacuum hoses and intake gaskets. Step 4 – The air intake boot or tube is used to deliver air to the intake system of the engine.
