]On my 86 vette I have a throttle body with three hoese. The middle hose is missing. Its sucking air and I can't find what goes to it.

I sent this picture over to a friend of mine that is big into the C4's and hopefully he can get back with an answer for you!!:confused:

That go's to some air valve on the right rocker panel its kind of hard to see. It will be hard to see with the runners you got so get a really bright flash light its under the # two runner facing forward. But I have no clue what the name of the thing it go's to though.

I dont know what that is. I just went and looked at mine and I dont have one of thoes. I have a spot for it but there is just a solid wall of metal there.

I'm pretty sure thats a return coolant line for the throttle body fast warmup. I'll look at mine when I get home but i think i deleted that on mine.

I found this on another vette the other day. I found that line on a crossfire vette up at autozone. that hose ran back to the valve cover on the passanger side of the motor.
