Oil light
The check oil light comes on when the engine is warmed up, It will only come on at idle (600 rpm) and will go off when revved up Any help would be appreciated

Idle should be at 650 or so when at normal running temp also. You don't have an aweful lot of oil pressure at a 600rpm engine idle speed. It is also possible that is what is setting it off.

Just a thought.
