Clean throttle body bore and throttle valve plate of carbon using a shop rag
and an appropriate cleaner. Refer to Engine Controls Repair Procedures -
Throttle Body Cleaning Procedure. This procedure may be performed at any mileage
necessary. Check to determine if the PCM calibration has been previously updated
to one that includes the update for throttle body coking. For 2003 model year
vehicles, look in the operating system portion of the calibration. For 2000-2002
model year vehicles, look in the engine portion of the calibration. If not, then
update the PCM calibration to the latest calibration.</P><A name=ss4-1527156><A
