    by working the butterfly open and closed to clean it,it threw the ICS (Idle control system) off in the computer.There is a Procedure to re-learn the idle.and it does work but you need to know what to look for.Thanks for your help!

    I have an 05 altima. The check engine light came on. It was a TPS code. I replaced the Throttle body Tps unit. The car was fixed as far as the check engine lite was concerned. But now I had a idle surge. There was a base I idle reset procedure I had to preform. I did this. Still the vehicle surged at idle. Now Im told only the dealer can reprogram my new throttle position sensor.Through there software. That is not attainable to the public. Ill let you know how it works out. What a joke! A throttle cable has worked without problems for years.

Your throttle gate is probably stuck open, allowing too much air to come in. When you put the throttle back together make sure the gate is closed. Hope this helps

Idling problem

check the air intake sensor and the O2 sensor for fouling or damage. If you removed the cat convertor the O2 sensors will not work correctly.

Cleaned throttlebody and now idle surges when fan is on

Did you disconnect the battery to reset the PCM while you cleaned the TB?
Also make sure you reconnected the small vacuum line on the side of the air tube.

Car cuts off while driving and while in park

The first thing I would do, is clean your throttleplate and throttlebody. The throttleplate builds up dirt as does the surrounding housing and it chokes off the air supply needed for maintaining idle. On 3800 engines, there is a screen that blocks access to the plate, so you'll need to remove the throttlebody and clean it from the backside. It's relatively easy and straightforward to do. Remove the mass air flow sensor from the top of the throttle body and clean the element with alcohol and a q-tip. Then spray the throttle plate and housing with carb or throttlebody cleaner and scrub with a brass brush. Open the plate by hand and scrub the housing. Wipe it clean and reassemble. See if that helps and let me know either way, whether its now good, or whether it still stalls and we'll work together if need be to rectify Idle Air Control motorthe IAC motor can close during cruise, and get stuck in the dirt that builds up in the housing. When you come to a stop the pintle may get stuck in the dirt, causing the stall. Then it frees up if it still has problems after this try changeingthe coils and module

I have a W124 230E has idling problem, and sometimes it goes off

Most likely caused by a dirty throttlebody! Remove the intake hose to the throttlebody and clean around the inside and the butterfly valve as well with some brake clean or similar product! Throttlebodies get gummed up by carbon build up effectively closing off the idle airgap under the butterfly valve!

I have a 1990 Tracker. When cold it idles very high, 2300 RPM, then goes to a surging idle as it warms up< 1400 to 2000RPM, then after it is warm it idles nicely. How do I reduce the idle when cold...

sounds like the idle air control sensor is bad or it could be the idle speed control sensor(module) both can be found on the throttlebody. but to be sure you can take the car to auto-zone and they will run a free diagnostic even if you dont have a check engine light there still may be a code stored.

My 2005 altima idles high and engine code

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

2000 Camry Starts but dies down right away


I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble
