well my friend's tegg idles at 3500.... but he noticed a big chunks missing out of the intake mani gasket.. when he bought the car.. it had a stuck valve... oh and this is a gsr.. well he got a new valve, put that in, and now it idles at 3500.. could it be the gasket? or what?

 

That could definately be a part of it. I'm sure it's ******* up the vaccum.

 

chunks missing out of gasket=problem within itself, even if its not the cause of the 3500 rpm idle and it probly is
