Idle Speed
WARNING: This page is about a different car, the 1994 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
Idle speed is controlled by PCM and idle speed control air by-pass valve on all engines. On most models, engine idle RPM is fixed and cannot be changed by standard adjustments. A scan tester must be used on these systems because control strategy and idle speed specification are controlled by PCM. See IDLE RPM SPECIFICATIONS.
Before performing idle speed adjustment procedure, complete a thorough basic inspection and self-test (KOEO, KOER, Continuous Memory self-tests) to confirm operation of sub-systems contributing to idle speed control. See QUICK TEST in TESTS W/CODES article in the ENGINE PERFORMANCE section.
