Default Fixed ZC wiring, now car revs to 4000rpms at idle and stays, what is the issue?

I found out I never extended my green plug to go to the EACV so I did and that fixed my surging idle. However now it revs smoothly to 4000RPMs and just sticks. It throws a code 9 (PM6 ecu). What is the problem, you think the idle screw is messed up making it rev that high. I haven't driven it anywhere since fixing the wires so I don't know how it drives but I was just looking for some help as people are tired of giving me ride and letting me borrow their cars.

Was the car a DX? Which throttle cable are you using?

It was a DX, but I got a Si throttle cable (minus the bracket) from the junkyard, its sort of ghettoed on, you think that is pulling on it a bit? I ordered an new OEM bracket so until then my car is slightly f'ed.

Check to make sure the cable is tight against the fire wall. There should be a plastic boot that holds it in place. Once you get it running do a visual inspection of the TB. Make sure it is not getting stuck open. Let me know.

Sounds like a plan.

If it is not stuck try to check your vacuum lines. One of them may be causing the TB to open up farther than it should at idle.

Hmmm, I have 2 vacuum hoses coming from where the MAP Sensor and that stuff on the fire wall is. I wonder if I have them switched, cuz one isn't even plugged in, the other is, perhaps I should switch them and see how that works.
