The throttle bodies on most newer cars are not adjustable for its idle speed. If the Check Engine Light is on, go to the nearest auto parts store and get them to pull the error codes from your car's computer. Post the codes back here and we can give you a better answer to your question

    I had a new throttle body installed now it,s running high idle when I come to the light it goes from 1000 down below 1000 but when stopped I had them change my gas pedal and I was having codes come up about tracking system and reducing power on the car I'm just asking is there a certain way to change the throttle body speed noticed there were six clips on the outside of it you could get back with me thank you here is a couple codes one is p1174 and the second one would be p2138

    sounds like you may have a bad throttle body sensor which is located on the throttle body itself it can happen, you can also have a faulty o2 sensor or clogged fuel injectors both will throw a p1174 code . If you paid someone for this work I would take it back to them and have them fix it as it was not fixed correctly

How can I fix high idle?

In theory once the desired idle speed is programmed into the management system, in the absence of such faults as air leaks, sticking idle air control valve and suchlike it should be impossible for the idle speed to be much different from the programmed value because the ECU should continue closing down the amount of air bypassing the throttle butterfly until the idle is around the correct value.

I think you need to go back to basics and double-check the work to ensure everything is as it should be. In the absence of mechanical faults and ignoring the possibility of electronic problems a high idle must be caused by too much air entering the engine, either because the idle air control valve is not closing properly or because the throttle butterfly is not closing fully.

It is worth noting air can enter the intake through leaky diaphragms, split vacuum hoses or faulty pcv systems. It is also worth checking the egr valve if fitted.

How do I adjust the throttle body on a 2007 toyota corolla?

Unfortunately many car manufacturers don't like it when people do it themselves, so they have a little b**by-trap they like to spring on you. If you replace the TPS, IAC, etc, the idle will many times no go back to normal and you will need to have the computer "relearn" so it can rest it back to normal! No real reason for them to design it this way, except of course to force you to go to the dealer to get it fixed! Nice little surprise they like to give their customers!

Code p1506

P1506 - Idle Air Control (IAC) Overspeed Error This DTC is set when the PCM detects engine idle speed that is greater than the desired rpm.
  • IAC circuit short to GND
  • Damaged IAC valve
Disconnect IAC valve and look for little or no change in engine rpm as an indication of a stuck or damaged valve.

Idles high,jumps high and low,cleaned throttle body,and still idles high,will come down but takes a minute or two,what could it beits a 2004,mag. v 8 ,4.7 liter

disconnect the negative battery clamp, and leave it off for 5-10 minutes-resets the computer and forces it to relearn the sensors-if the problem continues, your idle air control or the throttle position sensor are prime suspects.

Has low idle and wants to die when a/c is on when idling. Then when i accelerate, it sounds like it is shifting at high RPMs.

The low idle and wanting to stall is caused by a dirty throttle body, it needs to be cleaned thoroughly front and back sides using throttle body cleaning spray. Also while doing the cleaning, disconnect the battery to reset the computer so it will relearn to the newly cleaned throttle body.

1996 Ford Thunderbird V8 4.6L Idles High. When starting up engines does not idle down after warming up. When driving car just wants to speed up.

check your throttle body make sure all the springs are connected. your throttle body may be nasty inside and may need cleaning, it may be getting stuck. Throttle cable could be sticking or disconnected (there are two one pulls and one returns to idle IIRC)

also you should really search and become a member there if you are not already.

2500 to 3000 rpm idle

Change your Thottle positioning Sensor. My 93 lesabre did the same thing and i changed the TPS and it stopped.

Idle runs too high when I come to a stop, for about 5 seconds.

The throttle body may need to be cleaned. Take off the induction hose to the throttle and open the plate. Make sure the vehicle is not running. With the throttle plate wide open, soak a cloth rag with carb and choke cleaner and work the rag around the inside of the body especially where the plate's closed position is. remove the rag and spray a small amount of carb cleaner down the throat of the throttle body. replace hose and run vehicle at 1500 rpm's for a few seconds. This should fix the idle. It should be idling at about 800 rpms.

Idle at 1500 to 2000 rpm

Most likely the throttle body gasket (between the throttle body and the intake manifold) is leaking.

Loping and high idle

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