Ea82t Hose to air intake duct

Recommended Posts

When installing an intercooler i noticed this hose leading from the thermostat to the air intake duct (Hose number 7.)

 

What is the intention of this hose?? Can i just block it off?

that is the idle bypass line

you may want to incorporate a fitting for the line

it takes filtered air from above the throttle plate to below the throttle plate

Should only idle rough when cold.. after it warms up, the AAV doesn't do anything.

 

Mine is currently blocked off.. When I had the RX7 IC in there, there was a fitting on the IC just the right size, so I kept it hooked up. not a noticeable difference either way.

that is also the idle air control valve if im not mistaken.

 

IIRC, the IACV is a solenoid and screw on the back side with a white power wire and a black ground wire

 

it's good to remove the screws and clean off the carbon

hmm, makes a bit of sense there. granted, i am missing the electrical section of my fsm and never had any idleing issues other than too high, which is fixed. but i have no idea why i though that was the iac valve, i think its from selling ford iac valves all day at work. im used to seeing something that stands out.
