Needs new powersteering pump and its been sitting for a few months. pretty low on gas too. is that why it would be so low or is there another problem?
idiling at 650-750

um... my car always idled @ 700 dead on. perfect.
so the question is... why do you think that's low?

well....if you think it is low you could turn it up. it is just a couple nuts on the throttle body i think.
hmm really. i was always under the impression that the rpm for this car should idle at 900-1100. sorry guys
Sorry for the misinformation.
I don't understand why they would give you the adjustment there and also make the ecu control it.

ecu controls the idle. Just need everything working properly and the throttle plate/tps/ dash pot adjusted to spec and it will idle perfect all the time.

I'm unsure what you're talking about. If the throttle stop it's not there to control idle even though it effects it. If the factory air bypass screw on early model throttle bodies it's there to set the valve's pintle within the window of position needed for the full range of control. Does that make sense? Put simply, what Poodles said.
i think i understand what your saying.
to be honest i am not sure what a lot of the parts on the throttle body are there for, it seems like a much simpler design would have worked just as well.
i think i am looking at the throttle stop....well the second throttle stop. i will throw up a pic...
not sure if you can see that well but there is a ?vacuum? switch right below it that controls where the adjustment screw stops.
thanks for explaining btw

I believe that's just a dampener that keeps the throttle from slamming shut (I took that off mine, I like my throttle to slam shut :rofl
there's this thing called a IAC valve... it's a pretty simple concept

TF: That's a dashpot. As 89jdm said it slows throttle closing. The little check valve-like thingy connected to it makes air flow out slower than it flows in. It's an emissions device. By slowing throttle closure a little air sneaks past the throttle plate to completely burn fuel that's already been injected. See the TSRM for details.
Since it can hold the throttle open it also can effect idle speed. Yet another reason why stuff on the TB must be set up in a particular order with the TPS last. As for the idle control system being a simple concept it depends on how one chooses (or is able) to look at it. Like all things it's simple on the surface. In depth, not so much.
