Pretty sure any intake leak is a quite common cause for a high idle. That was my first thought, but you threw me off with the throttle cable / linkage info.

Yep. That screw is there as a connection point between the cable and the throttle plate. It allows adjustment for a slack/stretched cable. It is NOT to be used as a idle adjustment. The days of idle screw adjustment are long gone since carbs have been replaced with fuel injection. The PCM adjusts the idle via the IAC (Idle Air Control Motor). Likely his high idle problem is because he has that screw adjusted to where it is pulling the throttle plate open. The throttle plate should be fully closed while in park at idle. Adjust that screw out until it is.

So what was the verdict @drewtx154??
my guess besides the cable being messed with and/or a dirty iac, they get coated with carbon just like the throttle it can be taken off and and cleaned and the cavity inside the housing can be cleaned as well

I think as well at this is the problem.
I would remove the cable from the throttle again and start the engine without the cable.
if you then still have a high idle, you have an air leakage or a problem with the iac.
If the idle is okay, you have tension on the throttle or cruise control cable.

Haha verdict is that I'm an idiot... But seriously after I read over one some of the initial comments posted on my thread I went and looked over the throttle cable adjustment screw and realized I had taken pictures of my engine before I ever put my hands on it and was able to determine that I had my throttle cable adjustment "screw" (idk if that's the proper term or not) set in the opposite end of the spectrum. So I readjusted according to my pic and everything was all good. Sometimes I jump to conclusions way too early! That's a personal problem I gota learn to tone down lol. But thanks for asking... And thanks to those that chimed in to help a novice

But I got another issue (several actually)....but one I'm kinda stumped on.... Idk if I should start another thread or just keep goin on this one??? But I can't seem to figure out how to release my spare tire. I've watched plenty of videos and read several threads on the crappy design of the safety latch mechanism being rusty and etc.... Problem is I can't get mine to come down at all. It is completely stuck at the very top with zero slack in the cable. I've jammed a screwdriver up inside the mechanism like the videos show after spraying it down with PB blaster and couldn't get it to release. Only thing I can think of to do next is to somehow either cut the cable holding up the spare tire or unbolt the winch mechanism but I can't get anything close to the bolt where it is mounted on. There seems to be no room from the top side of spare to get to the winch... So idk what to do... Every video I've seen has been able to slightly lower their tire a few inches or so but mine won't move a millimeter.

Are you using the spare tire kit? It’s a square rod on the end. I believe a 1/2”
square female end goes in the hole, put 2 links together shove the female end in the hole, turn the rod slowly and push at the same time and you will feel it slip in and lock in place.
if that does not happen pull the rod out and look in there with a flashlight and see if there is anything blocking the hole, dirt/rock, whatever.
once the rod is in place turn it counterclockwise
if that doesn't work then try this
Hopefully @Fless sees this and starts another thread. don't really want a completely, non engine/drivetrain problem, mixed with this thread.
