My '2000 Grand Am has an 2.4L engine and 78000 miles. Recently, the idle speeds, parking idle and driving idle, go higher from original 600 RPM to 1000 RPM. Also, at low speed coast (release gas pedal), it keeps higher speed and takes longer time to slow down. I measured resistance of air temperature sensor, it has a reading ( I don't know what is a normal number). What is prolem? Please help. Thanks. James Z
