Idle relearn is necessary after replacing an intake manifold gasket because it affects the engine's idle speed and can cause drivability issues. A scan tool is required to perform the idle relearn procedure. Refilling the cooling system, torquing the manifold bolts, and checking the air cleaner do not require a scan tool.
