Anyone know where on the stock throttle Plenum for 96-98 throttle/idle adjustment screw is? I've checked all around it.

Are you trying to set/adjust the idle? If so, are you aware that the idle is not adjustable via "a set screw"? The idle is controlled via the PCM/IAC and is not "adjustable" except by re-programming the PCM. Therefore if the idle is incorrect this likely means that something else is wrong.

In general trying to resolve idle problems by adjusting the 96+ idle stop set screw is a bad idea especially if not done correctly. Likely well create more problems than it resolves.

Here's some more detailed information on how to trouble shoot idle issues.
