Idle Air Adjust Spacer?

Yeah that thing does work it allows more air in for the fuel you are now using at idle. Pulling back fuel at idle will also get rid of the problem. I bought my air adjust spacer for free its just not adjustable. Just drill the same size hole in the throttle plate the same size that is in the stock throttle body. If you have more than a 306 you may want to drill a larger hole.

So how big is the hole in the butterfly in the stock throttle body? I don't have my stocker anymore. Like the size of a ball point pen tip? My surging idle isn't that bad actually. Not as bad as it used to be...but I'm still thinking of drilling a small hole in my BBK 70mm TB to help out the idle a little.
