Yes, that’s correct. The nut broke off and took about quarter of the bolt with it
Gen 3 Throttle Idle Issue

I’m going to do the job over again in a few days, with a torque wrench. I just have one more question to ask. Do you put rtv sealant on your intake gaskets at all? I didn’t use any, but I would like other opinions on it. Because some guys say do it, and others say to use only the gasket.
I just finished the job yesterday. I used a torque wrench and didn't use any RTV, which my FSM didn't call for any. Once I got everything connected and put back together I started her up, and the gas smell came back. This time it took about 40 seconds to show up, rather than the usual 10 seconds. And the throttle body still goes haywire. My buddy and I thought we should back it out of the garage and run it for a little, but once put in reverse it almost stalled out. Which to my understanding is very much so a common faulty throttle body symptom. I never put it in gear after I did the intake job the first time up until now. Now my thought is I definitely must have 2 bad throttle bodies, the one I had just purchased (used) must be faulty as well, so that's getting returned. I did not notice any fuel injectors out of place and the electrical connectors where in place, and I did not notice any suspicious damage to any fuel line in any area I had to tamper with. Could all this be from a bad throttle body? I find myself asking that, but I don't know if the fuel fume thing even relates to the throttle body.

Hmmm, did you fix the bolt that was stripped out? Are there any codes? Did you replace the spark plugs?
There should be a method in the FSM to test the throttle body. I think I'd do that before you replace it again.

You followed me, so now we're both lost
The FSM should have a troubleshooting section for the wiring connector and throttle body. It does still sound like it has a vacuum leak, but hard to know with the throttle body acting strange.
The fuel fumes may be the engine flooding with an incorrect throttle position reading. Do you see any leaks from the injectors under the intake manifold?
There maybe some Gen 3 owners near you that could help. Unfortunately I am on the opposite coast.

Not sure if you checked this yet or if it would matter, I believe your throttle body is fly by wire, have you checked your pedal position sensor? If that was sending a bad signal maybe it could be causing the thing to spazz out. What does your gauge tell you TPS is at when you start it up? Are your fuel trims still out of whack? I have a car with fly by wire and with key on engine off and gauge plugged in I can actuate the butterfly by pressing gas peddle, verify % open on the gauge and visually see it operating. It’s helpful to have someone to help out since you can’t see butterfly while sitting in the car to press gas.

I did fix the bolt and nut, and I went ahead and replaced both while I was down there. And I will look into the FSM and see what I can come up with. Thanks!
I sure hope it's just the throttle body, but I'm trying to not get my hopes up haha. I looked at the fuel injectors while I was down there, and one injector (cylinder 5) had a little more dust around it then the rest, but not much. About 2k miles ago the previous owner took it to a shop and got the fuel injectors cleaned. And where I live I see little to no 3rd gens or monteros in general, it kinda sucks but there's something satisfying about owning an uncommon car.
Thank you for the help, and I will need to whip out the OBD2 again to check my fuel trims and TPS position. I'll get back to you on that. I will also need to check the pedal position sensor, would you know where that would be? If anything I will find it in the FSM. Thanks you!
On my car it’s inside the cabin, up under the dash / foot pedal area near the pivot point of the gas pedal. I have no idea where yours might be.
My TPS reads at 6.3% on accessory mode, and 7.1% while started. For some reason, my OBD2 reader wasn't reading my fuel trims because long term and short term where both at 0, and I didn't want to wait for them to show due to the nauseating fumes. I did run the car longer than I usually do and noticed quite a bit of vapor or smoke coming from the exhaust outlet, followed by a film of residue covering where the smoke was hitting the garage floor. I smelt into the exhaust and could smell a fuel odor of sorts.
The video you posted of it spazzing out, does it not do that if you turn key right to crank and start it up? Also can you pull the intake tube rubber so you can see the butterfly and operate it with the pedal, key on engine off, to verify that it moves smoothly through the whole range?
I guess I have not tried to crank it right up, but I will try that today. And I did not know that you were talking about physically seeing the butterfly valve, that sounds like a great idea! I'll get back to you with the results... thank you!
