LS intake manifold

[racintweek]

on the manifold under the throttle body there is an opening with two passages
what the hell is it for?

and can i disconnect the coolant hoses that go to my throttle body without complications?

those coolant lines control the fast idle assembly. go for it.. connect them together but be prepared for a rough idle if it is cold out.

i have mine blocked off too. but the car is not run in the winter. if you live in arizona, go for it. if you live in alaska, you better not.

word.. same with me.. i dont have mine connected either, but my car is only run like 6 months out of the year.. maybe 7

what about the opening on the manifold?
