the 90 degree hoes that comes off the throttle body of an 88 motor.....where the hell does it go?

 

where on the TB is it? Could be the vaccuum line to the FPR or part of the emissions system.

 

on the bottom.....its def a coolant line b/c it has dried coolant in it....its about 1/2 inch in diamater.....not a vacuum hose too big

 

Could be a throttle body coolant hose. I can't remember the diameter of it. Gotta pic you can show me? The TPI has two coolant lines running through the TB, one for TB coolant, the other I'm not sure of but they both run to the heater hose cylinder (whatever that thing is called).

 

well i took out all my heating stuff......so can i just plug this hole?

 

I'm not sure cause I've never done it. I'm not sure where the line returns, so I wouldn't plug it up until I can find out where it returns, then I'd run it like a bypass.
