Why would RPM stay high when accelerator is released yet when you tap the gas it will drop down to normal idle speed?

Possibly dirty accelerator linkage or sticking throttle body

butterfly. Clean all the linkage and the inside of the throttle

body, paying close attention to the butterly. Use only a spray

cleaner that is safe to use with emissions sensors. Do not use a

product such as WD40.
