On a '94 3VZ-E would there be any negative affects on anything if the throttle body coolant lines were connected together rather than to the throttle body?

 

i cant see why it wouldint work

 

it will idle at 1500 or 2000 rpm all the time

 

How does it affect the idle speed?

 

yes how would it affect the idle speed?

this is a common mod with the LS1 (and probably with all gen IV small blocks) which are obdII and more complicated than our simple engines...

 

the addition of a throttle body coolant bypass. routes engine coolant through the throttle body to keep the throttle plate from sticking in extremely cold weather. This has the rather obvious result of heating up the throttle body and possibly the incoming air. Since hotter air is less dense, the engine produces less power...... that help explan it at all ?

 

I was planning on doing this myself, but never got around to it. Once I can get the ball rolling on my map conversion this is definitely getting done as well.

 

Could the bypass be routed through a valve assembly so you could run bypass in the summer and normal in the winter? Which lines are the coolant heater lines?
