There is no idle adjustment screw on this engine, which is normal for EFI engines. The idle is controlled by the car's computer. It does this by controlling the Idle Air Control - IAC - valve, which should be checked in your case. See here p271

There is a throttle stop screw, not the same, on the throttle body, which you may be thinking of, p263. This does not directly control idle speed.


Also the A/C, if any, can affect the idle if the A/C idle-up switch has failed. If testing this switch, do so when the engine is hot, as that is when they fail. See p295

Here are step-by-step instructions for the removal and re-installation of your ignition cylinder on your Toyota. Hope this sheds some light on the subject and solves your problem. Have a great day!




  1. Disconnect the negative battery cable. If equipped with an air bag, wait at least 90 seconds before working on the vehicle.
CAUTIONSome models covered by this guidemay be equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in .
  1. Remove the lower steering column cover. Unfasten the ignition switch connector under the instrument panel.
  2. Remove the screws which secure the upper and lower halves of the steering column cover.
  3. Turn the lock cylinder to the ACC position with the ignition key.
  4. Push the lock cylinder stop in with a small, round object (cotter pin, punch, etc.).
On some vehicles, it may be necessary to remove the steering wheel and combination switch first.
  1. Withdraw the lock cylinder from the lock housing while depressing the stop tab.
  2. To remove the ignition switch, unfasten its securing screws and withdraw the switch from the lock housing.
To install:
  1. Align the locking cam with the hole in the ignition switch and insert the switch into the lock housing.
  2. Secure the switch with its screw(s).
  3. Make sure both the lock cylinder and column lock are in the ACC position. Slide the cylinder into the lock housing until the stop tab engages the hole in the lock.
  4. Install the steering column covers.
  5. Connect the ignition switch wiring.
  6. Connect the negative battery cable.

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

Idle adjustment problem


If the idle mixture screw ( idle screw) does not make a difference it is because the idle circuit is blocked . Check the jets for dirt / water . Blow out the system with compressed air.. The mixture is already set by the time it gets to the screw and you are only increasing or decreasing the volume allowed into the engine . There will be no "O" ring but there should be a spring under the head of the screw.

Adjustment Idle


There will be a screw on the throttle shaft that can be used to adjust idle rpm but you should find out why the idle mixture screw is not making a difference. Check for vacuum leaks in all the lines and manifold gaskets.

Idle adjust


It should have a base idle adjustment and could also have an idle speed control motor.
The base idle screw should be on the driver's side of the carb. You would also have a fast idle screw on the choke.

How to Adjust idle RPM for a 2003 honda accord. some people were talking about a screw on the throttle body. but I can't find that screw. How do you go with adjusting this and where to find it ?


First, you shouldn't adjust the idle. If the idle isn't correct, that means there is an issue somewhere - not that the idle needs to be adjusted.

There isn't an adjustment screw. To adjust the idle, you will need to move the TPS (Throttle Position Sensor) forwards or backward. To do this, you will need to remove the tamper proof bolt and replace it with one that can be loosened and tightened.

Hello I have a 1980 Ford Bronco 351 2bbl. Wondering if anyone knows which screws adjust what? Please if anyone has any ideas please respond. Thank you.


Here are some images that might help to assist you, and let me know if you require any further assistance.


Adjust the curb idle with the engine warmed up and the choke off.

The air/fuel mixture screws should be adjusted with the engine warmed up and at normal idle speed, then turn each air/fuel mixture screw in one at a time until the engine just begins to mis-fire, then back the air/fuel mixture screw out 1-1/2 to 2 turns out a half a turn at a time until the engine idle is the smoothest. (your vehicle might have restrictor caps over the air/fuel mixture screws to limit the amount of adjustment)

I am looking the idle adjustment screw on my 1971 350 cu. in. El Camino Carburator


Remove the air cleaner to access the carburetor.
Note the right side of the carburetor where the accelerator cable is connected.
The cable is connected to the accelerator cam which is stopped by the idle set screw.
The Idle adjustment screw head is pushing down on a spring, which should help Identify the correct adjustment screw.
Be careful not to adjust the smaller mixture screws, unless you have a vacuum gage.
If your Idle is too high you may get after run or knocking. I would set the timing then adjust the idle afterwards.
I hope this helps out since I do not know if the carburetor is stock or not.

How to adjust air fuel mixture on a 87 suzuki samuria


On any carburator,one screw is for the idle speed, the other the air/fuel mix.Start the engine and let it get plenty warmed up. Adjust the idle screw to make the engine run slow. Turn the air/fuel screw in until the engine starts to die then out till it starts running loady.You want the screw between these two locations. Adjust it till the engine runs the fastest. Now adjust the idle speed screw to about 1000 RPM.
I hope this helps you.
