P0420 CATALYST EFFICIENCY BELOW THRESHOLD. CATALYST IS DEGRADED DOWNSTREAM OXYGEN SENSOR FLUCTUOTES FROM 0.2 TO 0.7 VOLTS, 02 SENSOR VOLTAGE SHOULD BE MOST OF THE TIME A FIX VOLTAGE FROM 0.7 VOLTS. **RECOMMENDING** WARM UP CATALYTIC CONVERTER. COSTUMER APPROVED REPAIRS. AND REQUESTED OIL CHANGE.
STARTER CIRCUIT FROM IGNITION SWITCH TO STATER MOTOR IS OK. STARTER SOLENOID GETS POWER AND GROUND WHEN THE ENGINE JUST CLICKS. **RECOMMEND A NEW STARTER FROM DEALER**
