Missing Throttle Stop Screw (1 Viewer)

[dukester73]

I've got an '88 FJ62 and chasing down a rough idle condition. I was in the process of calibrating my TPS per the FSM and realized I'm missing the small stop screw on the back side of the throttle body. I haven't been able to locate the screw on any of the parts diagrams so in thinking it is part of a larger assembly (and not available on its own). Has anyone else had to source one? Anything special about it? It looks to be an M5 thread.

Also, if/when I do find one, I can't find any mention of how to set it correctly. Other than TPS testing and calibration, I see no other mention of this screw in the FSM. Searched this forum with no luck either.

Surely this has happened to someone on here at some point. Suggestions?

Even though it not the Dash Pot, I think the part is:
22216 SCREW, DASH POT ADJUSTING
22216-74010

I don't know the exact size, but I was adjusting my just a few weeks ago while installing a new TPS.

Dash Pot Adjusting Screw! Sometimes the biggest hurdle is knowing what some of these parts are called!

Thanks for the part number but, no surprise, it's NLA. From the diagram it looks like it's just a threaded stud and a hex nut to lock it down once it's adjusted. Should be easy to recreate.

This sequence sounds right to me...

-Loosen throttle cable
-Adjust throttle/dash pot screw to just before TB opens
-Adjust throttle cable
-Adjust TPS
-Check/Adjust Dash Pot
-Check/Set timing

If anyone has any further tips or comments please share. I'll get started on this tonight.

Thanks, -Duke
