    I have a 2003 Acura TL Type S with the same problem. At idle the car varies between 1500 and 3500 rpm. It is very dangerous, especially in heavy traffic. I have taken this car to a dealer multiple times in the past and it was finally fixed by a mechanic (at my third try at an Acura dealership) by adjusting the throttle cable where it attaches to the engine. He actually grabbed the cable wiggled it around while the car was running in park and the rpms were moving up and down like somebody was pressing the gas. The mechanic said he was familiar with that problem with these cars and knew right away what it was. That was back in 2007, over the last week the problem has re-occured.

1996 acura 2.5 tl upon start up the engine goes to 2500-3000 rpms then the engine rpms start surging between 1500 to 2000 then after several minutes it goes to a normal idle and runs fine.


Hi, I had the same problem, and is now fixed. Replace your idle control valve, and the idle problem will go away, and your car will be PERFECT!

Why does my 2000 acura tl stalling


Try cleaning the throttle body and Idle controll valve with seafoam or gummout spray and if it still stalls replace the Idle Controll (IAC) valve.
If the check engine light is on and this is a USA car, the repair may be covered under a warranty extension this car has till 150,000. This video could be helpful...

1999 Acura 3.2 TL has 87,000 miles changed spark plugs but starting RPM still low about 500; sometimes it takes two starts using gas pedal. Can you adjust Idle or does it need timing adjusted.


You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a couple of screws. It is an easy relatively cheap fix that you can take care of by yourself. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!
