ISSUE:
Adjustments to the base (hardstop) idle RPM are not recommended because they are not effective repairs for driveability concerns.
Improvements in the calibration for 1991 make such adjustments unnecessary.
ACTION:
Do not attempt to make throttle body idle adjustments. If service is required, refer to the procedures listed in the 1991 Engine/Emissions
Diagnosis Shop Manual, Section 2, to determine other possible causes for driveability concerns.
