do you know what im talking about?i have a 91 si intake throttle body on the y7 now.if you have the 91 si ecu and intake ect, when you put the Z6 intake on there THERE IS NO FAST IDLE CONTROL SELONOID ON THE Z6 INTAKE, LIKE THE 91 SI. MY QUESTION IS WHAT DO YOU DO WITH THAT SENSOR?ANY ONE.

 

i believe you gotta leave it connected so circuit is complete or else check engine light will come on and idle will be screwed up,the fast idle solinoid picks up vacuum from two points and compares them to adjust idle,so i was thinking,on mine,im gonna tap an vacuum fitting into the sensor and connect a vacuum line to somewhere near old sensor location,then it has a vacuum line leading near the throttle body,so im gonna pick up the vacuum off a tee near throttle body,maybe itll work like that,ill let u know,but be patient gonna take about month before i get everything together and running

 

there is no reason the light would come on i dont have it at all on my a6 intake its blocked off

 

what u do with the wires that go to sensor,left em hanging?

 

there is no fast idle on a std so there is no wires to leave hanging

 

i think d- man is right,any time you unplug a sensor you get a code!

 

then wut code would u get smart guy i dont have one and there is no codes so wut codes huh? u dont know wut ur talking about my idle is fine also

 

if there was no fast idle on a 1.5, then why are these wires hooked up?

 

ill find out give me five min .ill go out there and un hook one of them and see what it does-smart guy

 

On mine, they are just hanging. I dont get a code.

 

you got me on this one.he is right d-man.i went out with the car running on cut one of the wires and no change and no code on ecu.could have sworn it would have gave me a code.cool thanks SMART GUY!

 

it doesnt do anything thats why they got rid of it and ive never seen one go bad and if it was bad it didnt effect anything sorry to be cocky like i said i dont have one on my a6 manifold its blocked off

 

So what is the point of the valve. How does the car act without it? How do you block it off?

 

dont know?but i got no code on ecu and it runs the same.now i can use my z6 intake. THANKS SMART GUY -JDMB18HATCH

 

opps my bad,was checking all the codes in our ECU,well,there's no code for fast idle motor,only idle control motor,anyway,that good to know that car runs same,guess itll only effect it in real cold weather when engine is cold,once engine warms up,idle control motor takes over from fast idle motor anyway
