purpose of IACV?

[wed3k]

i know this sounds really noobish and a guy like me that is going into ITB's should know this but i dont

what purpose does this serve? what would happen if i went to remove it?
what woulkd happen? would the car just idle really low?

thanks guys

It's a "Intake Air Control Valve". If you disconnect it the car will run pretty funny, like half throttle the revs will bounce. also it will adjust the idle revs to compensate for engine load from things like A/C.

it just keeps your idle about where it should be regardless of load (mentioned above) or engine temp, etc..........makes sure the idle is about right no matter what the fuck you're doing

Pointless....Anyway as people already mentioned before me what it does. As for the ITB setup there is software that controls it. Dunno how to use it but several types of software can help it out. I think AEM EMS is one of them and there are like a couple more.

hmm, so do you think it is possible to have the car run without it?
because the only way i could use it would have to be a custom adapter plate.
like shown ehre

I'd talk to people around the forum that have (or had) ITBs.
2point6 & Mr. Mike are two people that I'm pretty sure have ran ITB's in the past. I think there were a few more as well...

I just cleaned mine the other day...and all I can say is damn! I had so much carbon deposits in there.....as soon as I flushed it out and cleaned the mesh screen in there, my car idles more smoothly than b4 and I also noticed a slight increase in gas mileage! I'm guessing all that carbon buildup, (14 years) and it was never cleaned during the engine swap so now my engine can breathe a little more better i guess? I'm going for the EGR and EGR ports next....

we bybassed it on a friends car and the outcome was like what was stated above. it was somewhat normal while driving, but it made the throttle super sensitive. the car would lurch forward when you let off the gas and vise versa. later.

so bypass as in not habving it on and the coolant lines would just be looped or whatever right?

he had a homemade plate similar to the one above and a coupler to loop the coolant lines. later.

the crazy thing is when i started taking my manifold off i forgot to tighten the iavc so it was loose and i had no drivability issues (no serious ones at least, idled okay)
