Normal idle on MOST cars is 850 RPM at normal operating temperature. If it is idling that high, you may have binding linkage or the choke is not fully opening. If it is BANGING into gear, you could cause other drive train problems. You may also have a RUN ON condition when you turn the key off.
In particular, the pitch of the sound is what determines the calculated RPM.The sound produced by an engine is complex and includes many harmonics. In addition, there is usually some extraneous noise mixed in with the engine sound, making the task of identifying the pitch more difficult. For these reasons, the Engine RPM program has a variety of settings and modes of operation designed to make the measurement process more reliable.
