SOURCE: 96 bonneville high idle when cold

check or clean out throttle body at throttle plate it may have carbon build up on it. also make sure air filter is clean and check or replace the intake air tempurature sensor.(iat) sensor. the sensor is under 20.00, the sensor is after air filter in the big hose to throttle body.

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.

2001 Taurus 3.0 dohc idles high sometimes and once in gear transmission seems to shift at idle.


I think it may feel like that because it is idling high. For you high idle problem there are a few thinks you can look at one a vacuum leak. Two look at the throttle body plate and idle air control motor. If the throttle body plate are dirty the seat for the idle air control motor my be dirty. I would try cleaning the throttle body.

Idole to high


If your idle is too high it can mean a few things with computer controlled engines. Most common problems relate to the sensors in your throttle body being dirty or faulty. If after your disassemble your throttle body and clean the throttle body and sensors you still have the issue you can adjust your idle through the Idle Adjustment Screw.

Idling problem toyota altis


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:
Idle Speed Control (Idle Air Control) Valve Removal & Installation To Remove:
  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.
    • Tighten 33 inch lbs. (3.7 Nm).
  2. Install the throttle body.

Car idles too high. Had a replacement idle control valve 3 months ago which resolved the same problem, but it has restarted again now.


check TPS (throttle position switch)connections and TPS switch are renound for issues may need adjusting base idle, also check pcv hole in throttle body base manifold area clean out throttle body also if carboned up
is also possible this idle air control valve (IAC) is sticky due to carbon build up clean with carby cleaner or some sort of solvent
