Yes it most likely is.You will need to remove th ethrottle body off teh intake, it is held on th ebottom of it by 4 phillips screws. you will also need a new seal for it, so get that before you take it apart.Remove the IAC and clean it out with carb cleaner, let it soak if need be.The design is know for getting gummed up and sticking.
