RE: oil pressure light flickers at idle
Ok I have an 02 intrepid but shouldnt matter, and I am studying out its manual. What my guess would be is either borderline low pressure (failing oil pump maybe) I assume your not loseing oil. From what Im reading the pressure switch is a normally closed pressure switch that when the oil pressure is about 4psi is forced open and breaks the ground to the engine pressure lamp. If you feel your oil pump is functioning properly then check the switch. If it was happening at other RPMS I would guess it might be a lose ground or something but if the conditions are consistant , its either pressure is borderline low from a failing pump or the sensor isnt functioning properly. Just my two cents.
