Stuck open injector. unplug them one at a time or pull the spark plugs and turn the key on and see which cylinder fills with gas. call a toyota dealer with the VIN and see if its a software issue

You are really onto it! Either the TPS or the cable from the peddle. Do check the cable first. Frankster016

SOURCE: 2003 toyota sienna idle problem

After about 100K + miles the idle air control valve (IAC) begins to collect carbon deposits that interfere with the movement of the spring-loaded valve. You will not be able to clean this without removal and dissembly of the IAC body. Use an emory cloth or fine sandpaper to remove the build up around the valve. This should free it up to rotate without binding. This is a temporary fix, of course, and will either require cleaning again or replacement of the valve. Getting to the IAC requires removal of most of the intake upto, but not including, the intake manifold. Total time is approximately 3-4 hours, but worth it. Good luck, and I hope this helps.

Either there is a vacuum leak causing the high idle, or
the IACV is bad or being controlled by the computer to make idle speed too high:

To change the IACV refer to the following:

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the throttle body. Idle speed control valve toy_cor-04-18-1187.gif

  3. Remove the 3 mounting screws from the throttle body. Remove the idle speed control valve and gasket.
To Install:
  1. Using a new gasket install the idle speed control valve on the throttle body with the 3 mounting screws.

Idle air control motor. Mounted to the side of the throttle body. Pull it, clean it and the hole it came out of. Brake clean and a tooth brush. If it still idles high, replace the motor.

My 2003 Chrysler mini van has black smoke coming from exhaust and the rpm's are going up and down without touching gas pedal

There is an Air Idle Control (AIC) located on the Throttle body. you could try unbolting it and clean it with throttle body cleaner or you might have to replace it. The aic allows the correct amount of air to mix with fuel

My 96 ford taurus revs high when starting then works it way from 1500 or more down to 800 but fluctuates from 800 to a little over 1000. When putting car in rverse or drive from park engine revs up to...

You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

How to find and clean the IAC on a 2002 Saturn sl1?

First disconnect the air vent to the throttle body. The TB will come off with 2 10mm bolts. Dont lose the gasket. Undo the throttle cable, and 2 vacuum hoses on top. Be careful not to lose the spacer on the vacuum hoses. Take the 2 10mm bolts out and remove the TB. The AIC is bolted on the side under the TPS throttle positioning sensor. It can be removed with a torex socket or screw driver. When you take this off be careful not to lose the O ring. Spray the plunger down with brake cleaner and spray the throttle body down too, especially where the AIC fits into the flange. When you are cleaning the AIC Dont push it in or force it to move. It's not supposed to move by hand. Now, the back of your throttle body maybe [will be ] carboned up, you must spray this and scrape the carbon off. Get all the dirt off and make sure the vacuum holes are clear and the flap closes flush. Replace the opposite of removal. What are the car's symptoms? Over idling? If so, take the can of brake cleaner directly onto the intake manifold gasket. Near the power steering pump and across . Spray this directly on while car is running. If the idle changes at all, your intake manifold gasket is shot. These cars are well known for this , that is why I added that info. I just replaced my own last week. Let me know how you make out. If this was helpful, please rate solution

In cold weather thecar starts`ok but the rpms go to 2000 and slowly returns to around 1200 and stays there

idle air control valve is suppose to let the rpms go high to warm the motor to normal temp,and then drop it to 1200 rpms

High Idle Issue

Sounds like the idle speed control motor is stuck, this could have been caused by the cleaning.

High hc

you may need replace the catalytic converter, but 1st do this, clean the throttle body and idle airbypass valve, change the oil before the retest as well, get it as hot as you can before the test, hold it at a high idle prior to the test, this may squeak you by, as a 20 year smog tech these are the thing I did, if all else fails do the cat conv.
