yes, there is a big flat head screw when you are facing the drivers side, from the pass. side. But before you adjust the screw, u need to unplug the IAC plug, which is very dark to see, and is reacheable from the drivers side, behind the intake manifold.

I found that the flat head screw is very shallow, creating it difficult to adjust, and the car shakes so bad after you pull the plug, thats its hard to tell how to put the screw driver in.

i gave up. it idles fine.
