They say you aren't supposed to, but on my 91 I just replaced the throttle stop with a screw and adjusted it from their. You may want to check codes first though. Also clean out your IAC and check the temp sensor(not the one for the dash the one that feeds info to the computer).

never put a screw in place to bump up your idle -it will throw your whole system out of wack. it's idleing low for a reason.if your idle is up and down check the idle air control valve on the side of your throttle body. if it's a steady low -could be a vacumm leak,or loss of fuel pressure etc.
