Throttle stop dampener

Postby DeadDuck » Wed Apr 04, 2018 5:08 pm

I was wondering if anyone knows how to adjust the throttle stop dampener? The screw has backed its self out, and now my idle is a little wonky. This is for a large port in an AE86. Thanks

Adjusting the throttle damper will not improve the idle. It only effects the throttle rate of closing. There is a rubber plug on the top of the throttle body. [ Assuming the engine is in good tune ] Under the plug is the adjusting screw you are looking for to smooth out the idle. If the problem is a high idle speed, search wax-stat. Davew7

My idle is nice and solid, the problem is, some days its 1000 rpms, some days 1100, and some days 1200. When I pop the hood and have a look, the throttle is resting on the dampener and not on the stop. I haven't ruled out a problem with the throttle body itself. I've had it apart and cleaned it, and it works fine in hand, but who knows once things get hot. I was just wondering if anyone knew the proper way of adjusting the dampener.

The damper should not be holding the throttle arm off the throttle stop. Its
job is to cushion the arm when you lift off the throttle so that the throttle plate
does not snap closed. Rather, the arm settles gently onto the throttle stop.

I haven't looked at one lately, but from memory there is a pinhole that lets air
out of the damper when compressed by the throttle arm. In any event, the
damper should compress easily and not prevent the throttle from closing fully.
If you can't free it up by working it by hand, you would probably be better off
to delete the damper. It was not fitted in all markets, so the engine should
work fine without it.

PS: I assume that we are talking about the damper. Some 4AGE's were fitted
with a vacuum operated throttle opener which is a totally different animal :)
