Have you verified that the throttle body is not getting stuck open? There is an adjustment on the intake manifold for the throttle cable, make sure there is a small amount of slack in the cable when closed.

You may also have a vacuum leak on the intake manifold somewhere.

What I would normally do is remove the intake from the throttle body. Check it out to make sure the valve closing all the way. Crank the car up and see how it's idling. Cover the throttle body with your hand. The motor should die quickly. If it continues to run or slowly dies out you have a vacuum leak. If it idles high still and dies when you cover the throttle body you have an issue with the idle valve.

Assuming this is your 97 GS

I just tried putting my hand over the hose from the air box it just sucks really hard and it still keeps going

You need to block off the air flow right at the throttle body to eliminate other areas that could leak.

yeah I realized that's what I needed to do I took those off did that it still runs so I'm fairly certain that it's a leak so

Tighten the intake, throttle body, and check and replace any and all vacuum lines that are questionable. In my opinion, that is all of them. These cars are old and the lines, although appear good, are still probably leaking from age and cracking. It isn't a lot of money and a maintenance thing. A spray can of carb spray can make it easier to locate any leaks as when you spray it in an area that is leaking, the rpm's will rise or fall noticeably.

Check your ecu my caps leaked and mine idled at 2k steady it took out the isc driver path.
