2001 Chrysler Sebring 6 cyl Front Wheel Drive Automatic 119000 miles

My 2001 Chrysler Sebring lxi idles too high (2.5 rpms) when you put it into drive it goes down, its only high when in park or nuetral. We know its not the throttle or timing. We know it has something to do with the air filter system its a sensor that connects to the air filter housing but cant figure out what this sensor is. Any advice?

Do you
have the same problem?

2001 Chrysler Sebring Idles too high

Too fast an idle speed. If an engine without computerized idle speed control is idling too fast and refuses to come down to a normal idle speed despite your best efforts to back off the carburetor idle speed screw or air bypass adjustment screw (fuel injection), air is getting past the throttle somewhere. Common leak paths include the carburetor and throttle body gaskets, carburetor insulator spacers, intake manifold gaskets, and of course, any of the engine's vacuum fittings, hoses and accessories. It is even possible that leaky O-rings around the fuel injectors are allowing air to leak past the seals. Another overlooked item can be a worn throttle shaft and a defective idle speed speed control motor/valve stuck in the extended (high idle speed) position/throttle position sensor. Also the throttle plate could be binding in its bore and kinked accelerator cable, coolant temperature sensor might not be operating properly misleading the computer that the engine is still cold and computer throwing fuel at it raising the idle speed.
