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
Getting this possibilities checked will help.Thanks.Helpmech.
