Anyway, cleaning the pcv did not make any difference.
Anyone have any other ideas what could be causing the occasionally hunting at idle when warm. The rev needle hovers between 0-1000 rpm and sometimes the car stalls. Rossco, any ideas????

PCV should rattle when shaken.
What
BOV is on your car?
If your
bov is sticking & not quite closing shut you will get these idle issues. Also check all of your vacuum lines.
Hunting - if it's not TPS related - will be caused by a vacuum leak somewhere (
Bov, vac lines, evap purge solenoid) - Check ALL vacuum lines that run into the manifold - follow them from the manifold end out. & track their complete path. pay special attention to the Purge solenoid under the manifold to the right of the throttle body when looking from the front of the motor.
