Theres a small, black grub screw on the throttle body, closest to the fire wall. This acts as a stopper for the throttle butterfly. By screwing it in/out it will adjust your base idle.

There is a dodge way ^^^^ and there is the correct way. The correct way is to get car to running temp. Turn off all accessories. Stop car and disconnect wiring to the ISC. Place a 0.75mm feeler between the throttle stops. Start car and wait 2 mins (for diagnostics to run). Once idle settles adjust as above if the idle is not 650-700rpm.

You can do this without placing car in to diagnostics but I would then only set the rpm to 600-650 (as the base timing is reduced when in diagnostics).

cheers
Scott

Yep, 0.75mm in thickness. Trying to think of a household equivalent. Maybe a credit card or the like would come close. Two business cards, maybe. Feeler gauges are probably $5 at super cheap. I have used the spark plug gap gauge off the champion spark plug tester ($2 at super cheap, actually quite a useful tool).

You dont need to bother with the feeler gauge. Just get it in diagnostic mode and set the idle speed with the IAC disconnected.

The feeler gauge is there for a reason. You need the throttle open a crack to allow for the ISC to raise and drop the revs properly. It needs an allowance above the idle speed and below the idle speed to control the rpm in all situations.

You might as well just do it the dodge way and just set it with the a/c on and forget diagnostics, etc. All methods will work to some extent, but the correct way is as I described.

cheers
Scott

Stockstandard is right, the feeler gauges aren't necessary. By setting the idle with the ISC disconnected, the butterfly will be open enough for the vehicle to idle correctly without ECU intervention. Then when accesories are turned on, the ISC can up the idle as necessary. My EF doesn't use an ISC at all, idle is a little low when cold, but once it warms up its fine.

The gauge is there to make sure the person setting it doesnt set the base idle too high (above the ECU's target idle rpm). If you dont use a feeler gauge and keep the idle speed on the low side of the range you get the same end result.

The correct method is with the car in diagnostic mode, the ISC disconnected and the .75mm feeler inserted.
