Are the 2 ones on the top supposed to be open?
Also, is there supposed to be a little opening on the bottom one or does it have to close completely?

Thanks!

the secondary butterflies - the ones which aren't open, start to open at 15% of the primary, so yes they should look like that

ITS THE ONE AT THE BOTTOM THAT IS SCREWING YOU. That gap at the bottom should be something on the order of 0.014 or so. You could drive a SUV through that gap in the bottom butterfly. It looks like that only if you have your foot partially on the throttle. Find the throttle cable and see if its dead tight. Its attached to your accelerator pedal, goes thru the firewall into the engine compartment, to the left side of your engine where it attaches to a bracket, and from there it attaches to the throttle linkage at the back of the throttle body.
That picture shows exactly what is causing you 50000 idle problem. Now why the throttle plate is cracked open like that, well I can't say why since I don't know what the recent history of the car is . First thought of anyone would be the throttle cable is too tight. Why? I don't know why it would be out of rig like that. Also could be someone is screwing with the fast idle cam etc, but from what you have written I can tell you have not done so since on the N/A it would require some hijinks to get at the screw. Trust me. That BOTTOM plate should have a gap very close to what you see on the top two.
Your pictures are very helpful. We need more people to get involved. If someone sees I'm giving out bad info...say so, please. And oh yes, the three vac hoses on the front of your throttle body are wrong. Well the top hose is ok, but the bottom one feeds vacuum to your solenoids and the middle one feeds fresh filtered air t0 your fuel injector air bleeds. What I saw was the bottom two doubled back into each other. If I do that to my car(I did for fun) the poor car gets all confused and cycles up and down from 1100 to near 100 and on and on. But thats not you real problem. THE THROTTLE PLATE IS CRACKED OPEN TOO MUCH ON THE BOTTOM BUTTERFLY. something like that. How about a good pic of the front of the throttle body showing the hoses ??????????

My first TII got stuck wide open, there was crap where the throttle cable hooks to the TB. I sprayed it with carb cleaner and it snapped shut.

If its idling at 5000 rpm, I don't think that bottom butterfly is open enough to do that. You may have a vacuum leak or something else.

FELIX WANKEL.....Could be very right. I'm holding a throttle body in my hand right now and the gap is very small on the single butterfly. I also realize that that could be a carbon buildup around the bottom of the butterfly and I'm just confused when I look at it and think there is a large gap, when there is none. So the air hose being off is a possibility. If you look at one of DCminas first post having to do with setting the tps, one of those jpg shows that the vac hose on the front of the throttle body are arranged wrong. So if those hose are wrong its possible for another to be on wrong.
