SOURCE: idle and stalling

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: idle to low

The idle is electronic, possible causes of this could be the idle air control valve, mass air flow sensor, and air hose from filter. You can verify if there are any leaks in your filter housing with a visual inspection, you can also remove the mass air flow sensor very easily and see if it is clogged with dirt.

SOURCE: 96 lexus ls400. Car idles high and runs rough

It could be a idle air valve, a loose, unplugged or missing vacuum hose or a throttle position sensor.

My 1992 lexus ls 400 keeps stalling and idleis very low


Look for a small electric motor near the accelerator cable and near the top of the valve cover.

It's call IDLE AIR CONTROL (IAC) motor.

It's job is to increase the idle when load is added.
Example: turning on headlight,turning on AC.

Testing it is simple.

Warm up you car for 10 minutes.

Locate the IAC motor

turn on loads.....AC,headlights,etc


The motor should move the idle up


If the motor does not increase the RPM then it can be stick.

Try to give it few gentle taps to free up the gears.

It can be clean if your are up to it.


This electrical motor is very expensive. Please handle it with care.

====

The other trouble spot are

old accelerator cable

TPS Throttle position sensor

====

I will do a simple tune up and gas treatment before starting to replace any parts.


Please post reply on the comment window.

2003 Lexus GS 300. RPMs at idle fall too low. Car stalls and actually died once today. Someone told me it may be a bad idle air control but I can't find that particular part for this car anywhere on the...


Low idle can be caused by many things, Air filter, spark pulgs, fuel filter, just plane bad gas. First thing would be to check the air filter. look at the rear of the car, do you have a blackish dust at the bumper around the muffler? That is a air filter thing. Not sure about an idle air control. If you do not have a check engine light on, most likely you do not have a bad engine control. Check the air filter.
