I tried to do this earlier, but couldn't figure out how to disconnect the hoses since there's little room to work. Any suggestions?

I suggest taking the air box off, if you havenít already this will give a little more room. You need some needle nose pliers or small pliers. You gotta squeeze the hose clamps and slide the down the hose. What I like to do in order to get the houses of is to take the pliers and squeeze the top of the hose. Then twist the hose back and forth and it should come off. Do the same for the other side.

Yeah, I finally got the bright idea to take the airbox off, now I'm just going to wait about an hour and a half for my coolant to cool down since I just got home.

Danzborin, thats ironic that you said that, I'm looking for a used one right now as we speak Also, while I'm waiting for my car to cool down, is it ok to use a plastic vacuum connector for this? I was going to buy a brass one, but autozone didn't have any.

plastic is fine just be careful next time you're working around it as the plastic gets kinda brittle from all the heating/cooling.

Cool, thats what I thought, I'll just put it on there and keep my eyes open for a brass connector next time I'm in a auto parts store or Home Depot.

I wouldn't even bother with the brass connector, just be careful next time you're working in that area.

Make sure you dont bypass the IDLE controller, only the throttle plate portion.

I just connected the two hoses on the sides of the throttle body, is that what you're supposed to do? I imagine I did it right, my car didn't have a fluctuating idle on the way home, and it seemed like doing this made a noticeable difference. I did have to buy a new fitting though, the 1/4" plastic fitting was too small, but a 1/4" brass one fit just right.. Odd..

Yeah just connect the hoses together. I would also cover up the sides of the throttle body, where the hoses used to be.

Here is a pic of mine its kinda hard to get a good pic of it, such a small space to get too, for a camera

What exactly does this accomplish - and at what cost?

Accomplishment:
It is supposed to allow cooler air to flow through the head since the coolant isn't heating up the throttle body 'valve' itself. Some people notice quicker throttle response.

Cost:
Well, it's a free mod unless you have to purchase a piece to connect the hose where it used to connect to the throttle body. You could just cap it off.

Cost: If you are in a cold climate, your throttle body valve could freeze up and not open (or close) due to ice forming where the 'coolant' heated it up.

I think that may sum things up. There are some older long threads on this here.

Thanks, I think that covered it. The "cost" I was referring to was your last point. I didn't mean money, I just figured those lines were where they were for a reason.
