There are 2 adjusting screws new the metal air intake body. The Phillips is mounted by the dual cables for the throttle and and if for adjusting the intrenal butterfly ONLY - DO NOT TURN IT!!
The IDLE speed is adjusted by the slotted screw (uses a straight screw-driver)- NOT Phillips head screw on the air intake housing. This screw in in the metal body of the air intake. I asked a local deal service dept and got great advice: Turn it clock wise until you hear the idle speed slow, check the RPM's.. should be appox 900rpm. Turn the screw 1/4 turn at a time - WAIT 30 secs for the onboard computer to adjust... still too fast? Give it another 1/4 turn until you get the idle rpm to appox 900rpm.
it MAY run a little rough on cold starts after this adjustment: IF So turn it back COUNTER_clock wise and 1/8 of a turn at a time to 'tweak" the cold start. I did it after a few days of trail & error..
good luck!
