Idle Speed Setting Procedures
NOTE:
For Step 6, if you must turn the throttle stop screw in, shut engine off, make estimated adjustment. Start engine and repeat Steps 4, 5, and 6
before continuing. 3 4.9L Calibrations: 7-52ER-, 7-52JR-, 7-52KR-, 7-52MR-, 7-52QR-, 7-52RR-, 7-52ZR-, 7-72JR-. 4 All other 4.9L
Calibrations.
NOTE:
For Step 12, a condition may occur where the engine rpm will oscillate. This can be caused by the throttle plates being open enough to allow
purge flow. To verify this condition, disconnect the carbon canister purge line and plug it. If purge is present, the throttle plates must be closed
until the purge flow induced idle oscillations stop.
