Greetings all

I am new on the forum, own a 92 Geo, hatchback, 4 door, AC.
Live in Ohio.

Does anyone know the procedure for setting the throttle stop screw?
I rebuild the Throttle Body and want to get the butterfly closing correct.
The service manual only shows the TPS adjustment.

I am assuming that the butterfly is closed just enough to expose the idle
air ports in the throat. Is this correct or is there a feeler guage adjustment to supplement idle mixture.

Many thanks
Joe

I'm assuming there's no supplement to set the throttle stpo screw, cause it's a factory setting. But, the TPS adjustment instructions will help you set it. Put the feeler gauge between the throttle stop screw, and adjust the throttle stop screw till your ohm meter reads what's stated in the manual. This will work fine if your TPS hasn't been played with.

Thanks Geosukigti,

Unfortunately I left the throttle cable attached, as I was removing the engine, silly me. This did some bending to the throttle assembly.

I did manage to get her running last night, she hunts on idle, which is a good sign at least I know I am close. A couple of more hours tinkering and I should have it right.
