Car idling rough and startup and stalls
Hey guys i have an 03 CL and last night while driving home after a long ride on the belt parkway ( doing 70 ish ) i stopped at a light and my car started to shake badly and stalled. I noticed if i keep my foot on the gas while starting and driving it drives "OK". But it i let it idle it will drop to 0 RPMs and just die. Any ideas what this is? I am worried that my engine is bad or something. I have just crossed over the 50K warranty also. My friend said it might be my fuel injectors ( they need cleaning ) but doesnt that mean all 6 injectors have to go bad for a problem like that to happen? Has anyone experienced this before? The "Service soon" light blinks on startup for a couple seconds and goes away. Check engine light is not on.

1st, the Maintenence required light has nothing to do with the problem. That light is activated by a mileage calculator, it isn't linked to any ECU diagnosis.
2nd. I had the same issue as you before and was told to check the IAC (intake air control) valve on the throttle body. Basically the car isnt' getting enough air at idle so it stalls. The valve should be cleaned/adjusted/replaced.

It is located under the throttle body. The easiest way for me to replace it without pinching the rubber gasket, is to unbolt the throttle body. Flip the throttle body over and removed the two screw on the IAC valve. Supercharged is slightly harder because you don't have enough clearance between the screw and the supercharge inlet housing.

sgmotoring's reply will answer your question. I need to do the same thing.
