Question about 2003 Lexus Gs 300

1 Answer

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 web. Does it sound like this part is the problem or do you know if this part exists on this car?

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.

My car is idling up and down


Engine stall or RPM fluctuates at idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Have you tried to replace the fuel filter? Had this problem on my Ford. Went nuts trying to figure it out, til my dad told me what to do. That was it. I hope this helps

Car will not idle 2002 lexus gs 300


if it drives fine off idle then I would suspect the Idle air control valve.
If its hard to start unless you put your foot slightly on the gas then again I would suspect the IAC

2003 lexus gs 300 makes loud grinding noises while air conditioning is running. The noise lessens when pushing on the gas, but gets louder when idling or in Park and Neutral gears.


One of three things. I would start with removing the belt and checking the idler and tensioner pulleys to see if they are running smoth. The third item would be the ac compresor brg.

2003 Ford Taurus wants to die when coming to a stop


TRY THIS AND LET ME KNOW IF IT CORRECTS YOUR PROBLEM
Here is the most common cause of surges and stalls at stops and low erratic idle speed and 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
