If anyone knows why maybe its doing this I would rep greatly!!! I'm going to Atl dragway tonight so sooner the better THANKS BRIAN


on the back of your UPPER intake manifold there is a rubber hose that goes into the pcv valve located in the back on the block/lower intake near the tranny, make sure thats hooked up also

and the 2 lines that go into the throttle body for the coolant should be simple to fix, id make sure the gasket was put on properly, the gasket should still be useable since you just had put it on, there really isnt any way to get the vaccum crossed with them 2 antifreeze hoses....
