intake switch.

There something fishy about that intake. What are the holes for?

I have the same intake on my engine and there isn't any holes there... just wondering if that cause the problem. That port is connected to the exhaust so getting it out with a vacuum would be route I would go. I know that stuff is sometimes very hard.

I bought the Felpro gaskets that blocked the ports all together... so I believe you don't need to even worry about cleaning the port out. Those ports help to heat up the air/fuel mixture on cold mornings.
