Actually, disregard the third paragraph above as it likely won't affect your situation.


And w/regards to the secondary throttle plates the set which is furthest from the intake are the most important as when they are closed it prevents additional air from passing through the throttlebody even if the other set of secondary plates are opened. W/the intake off the first set of secondary plates should be closed. There are three vacuum hoses at the front of the throttlebody. To the left of these hoses by about an inch lies a spring encased around a shaft and the spring is large enough to fit around your index finger. This is the rod which is tied to your secondary plates. This spring has a wire which sticks out and is tied to a small looking bolt. This causes tension in the spring and keeps the secondary throttle plates closed.

If you were to post some pics of this part of the throttlebody then you will be helped.

It looks to be modified.

So I messed with thermo wax and adjusted throttle screw and throttle body screw on top and idle dropped to 800-900 for 5 seconds then kept going down and just stalled you think if I mess with them and adjust it ill be good??

If you look in the factory service manual it will provide you with how the throttlebody should be set up according to spec. Try to get it into spec and go from there.

So it appears to be that my throttle is stuck slightly open after putting a ratched and turnin right idle dropped straight to 800-900 and is idling fine but when I step on the throttle and let go it goes back down only to 1000-1300 so what would I need to do to fix the throttle to go back to factory idle?

Check the throttle cable to see if it is too tight as it should not be taught at all so try loosening it. Also, if you have cruise control then check that cable as well.

My throttle cable is actually loose. Kind of really loose

If you have to force the primary plate to close so it idles properly then obviously something is holding it open. So, set things to spec (especially the fast idle cam/thermowax unit) according to the FSM and try loosening the throttle cable regardless of how loose you think it is as it takes all but a couple of minutes to do.
