Here's a question that is a little of topic, but deals with the same situation. I pulled the IAB last night and cleaned the ports on the side of the throttle body. I put everything back together and now the surging idle is worse.
While I was cleaning, I decided to pull the throttlebody and the gasket was horrible.
I figured this might be a part of the problem so I headed right out to the parts store and bought a brand new gasket, but this is the thing:
Do I need gasket sealant for this application?? I could not tell because everything got soaked in coolant. The guy at the shop said I should get it and sold me a tube, but I thought I would get some feedback before I started.
Any hints??
