Default is there some sort of mechanical choke or is my car messed up?

alright ill go through what i did step by step. 1st i took the sparkplugs out, and cleaned all the crap off them with a wire brush. but i only had one out at a time so i know i got the wires back on in the right order. next i sprayed some low pressure water all over the engine bay and scrubbed any dirt i could find off with the same wire brush (trying to prepare for a car show). well after i had done all that, and given the engine about 20 minutes to dry, i started it up to pull forward into the shade so i could keep working. when i started it, it started really, really rough, and when i revved to about 3500 to pull forward, and i got there and hit the clutch, the car still stayed at 3500, instead of dropping back down to idle speed. i gave it a quick punch of the gas to see if it would stop, and it revved up to about 4000 when i hit the gas, but when i let off it held at 4000 for a good long while before dropping back to 3500. i shut the car off and restarted it, and it started roughly again and revved back to 3500 and held there again. i disconnected the negative battery terminal for about 10 minutes then reconnected it and tried again, same thing. is there some sort of mechanical choke/throttle adjustment i could have bumped when i was scrubbing, or did the water mess something up? please help.

whoa, i figured out the problem! now how do i fix it?

okay there is this doohickey under the hood, for lack of knowing what its called, im gonna refer to it as "the doohickey". its the thing that the throttle cable connects to, the little spring loaded lever off the the side of the throttle body, when you hit the gas the cable pulls it down, or you can reach in and push it down with your fingers, and the car will rev just the same as if youre hitting the gas pedal. know what the doohickey is now? well for some reason its not returning to full "closed" or "off" position. when the car is running, and idling at 3500, i can tap the thingy with a wrench and make the car idle back down to normal, but when i rev it up again it stays revved up. it returns "closed" enough to drop to about 3500, but thats it. so how do i get the doohickey to close fully again?

Is it stiff? Maybe you washed the grease out of the joint that it pivots on and started sticking.

im thinking thats what i did. i just tried taking the nut off the end of it so i could spread the spring coils out a bit and silicone lubricant-ing the hell out of it, now i can tap it all the way back down to normal idle, but when i rev up it still stays up. how would i go about "re-greasing" it?

Does your car have Cruise Control?
Is the cable tight at the Throttle Body?

Follow the Cruise Control cable up to the Actuator and see if you popped it out of the fitting when you leaned against it. It will just pop back in.

nope, no cruise control

the throttle cable doesnt have any slack in it, but the little lever that it attaches to (red) has about an inch of movement before it contacts the other little lever (blue). the blue one is the one that i can tap down to make the car idle down.

this shot shows the range of movement before the "red" lever, the one connected to the throttle cable, contacts the "blue" lever. the "gap" is the range of movement, if i dont push the red lever down, this gap is on the bottom of the blue in between it and the part of the red that wraps around. unless im mistaken, there shouldnt be a gap. its like the blue lever isnt returning completely down when the red ones does. the further i tap the blue lever down, creating less gap between the 2, the lower the engine idles. but it wont return on its own past this point.

A possible reason for why the car is running so rough...you may have gotten the air filter clogged when you washed the car. Do you have a stock intake? I'd suggest taking it apart and checking to see if anything is plugged up

oh damn, i forgot about that paper towel i stuffed in the end of the intake to keep water from going up it while i was washing.

funny how something like a wadded up paper towel does a great job of sucking up the smooth aftermarket intake tube, then gets clogged in the throttle body, preventing it from closing fully.

okay, problem solved!

Oh boy.... You ahve no idea how lucky you are that you didn;t use a shop rag and have it get sucked past the throttle blade. I have seen pics of people that sucked a shop rag into the engine. It bends valves bad and pretty much destroyes the engine.

Yes.

I always put a plastic bag over my cone filter and run a piece of wire around it before I spray my motor....
there's no way i can forget to pull it off. I always start the car immediately after rinsing it too, so it warms up and evaporates any standing water beofre it soaks in places it's not supposed to be
