IAC/ISC(idle air controller) operation advice...

[trak-shuhnREX]

i have installed the hks vpc and gcc and had to switch to map sensor therefore eliminating the maf sensor.now that i have removed the whole turbo intake system i was forced to install a catch can as my valve cover breather was just open shooting out smoke.with that done and system working properly as to collecting oil i have the iac vac port open.

main question is that does the IAC pulls as vacuum?

Err... what?

If you're running MAP, put a filter on the ISC and call it done.

I would run a tube to a cooler part of the engine bay or at idle the only air the motor will be getting is the 200F+ air from right on top of the motor.
