Im having some trouble figuring out where to rout the coolant lines and vacuum hoses, when i got the car the iacv and starting air solenoid were missing all together and the idle was a little rough. The car needs a tune and has stage 2 cams in it so idk how much that has to do with the idle problem. Ive also read that some people delete their iacv and starting air valves all together. Any help is appreciated
