Today I changed the plugs and wires and air filter in my 2003 sebring sedan
2.4 DOHC with 162000 miles. After I put everything back together, I started the car and it is idling at 1700 rpm's in park. Any advise would be greatly appreciated, do you think that the throttle body needs cleaning, or the sensor has gone bad.

 

Check vacuum lines in the area you worked on. May have knocked one off causing excess air that the PCM is adding fuel to compensate for.
