Idle speed is fine aside from a short period of surging when warming up.
The problem I'm working on is that for the NJ smog test, HC is a little too high at normal idle speed.
In this state they sniff the tailpipe on non-OBD-II cars at two engine speeds to check emission systems - idle and what they refer to as "fast idle" (about 2500 RPM, really around cruising speed).
The car passes the 2500 rpm test by a wide margin, but is failing by a small amount at base idle.
