I have done the exact same mod, bypassing the coolant going thur my intake mainfold and my tb... Its lumpy when its cooler than usually 70 degrees, but anything above 70 its fine. Its horrible in 40 degree weather!!!

So now this winter i did a little mod, hoping to help stop that. I will find out maybe tomorrow when i start up my car for the first time in 6-7 months!

Hope everything goes good..
