Or get another jeep, LOL. Steel filled epoxy has outlasted every rig I used it on, even used it on a carburetor once in wet gas areas.

I like that idea.

A little luck and you can remove and reinstall that screw if you don't over tighten. Grease the back side of the TPS just in case some of the epoxy oozes or spreads.

I've used this trick a lot, especially for stripped out plastic screw holes.

Epoxy threads hold better than you'd think.
Sounds like what I might have tried!!!! Love the grease idea!! I would also be inclined to fill it with steel filled epoxy, then drill and thread it for such a light duty screw. But I like your version better. Might be hard to fill the hole properly with the epoxy for a drill and thread, but then again, a fine thin pick tool might work.

I would never have tried a heli-coil on something so small. But after reading this thread, who knows.

Obviously an over sized screw seems to be an option too.
