TB coolant bypass Question
Already did the mod, but I did not block off old coolant hookup tubes that come out of throttle body, could this cause a vacuum leak?

I did this to mine also, there's no vacuum problem with these since its coolant only. I did go to my local CarQuest and picked up some rubber plugs and put them on. Purely for looks only.
