Message	EC 220-222 in the FSM Also, Check your front O2 sensors: 9. Start engine with the ECU in MODE II to enter MODE II - Heated Oxygen Sensor (O2) Monitor . The ECU is now monitoring the left O2 sensor. Warm the engine to normal operating temperature, then run at 2000 rpm for 2 minutes. Check that the LED blinks (or the check engine light) more than 5 times every 10 seconds at 2000 rpm. Check Front O2 sensor as well, EC 150 1996 FSM or 1996 FSM Did you replace with an OEM sensor? When I installed I used new OEM front and rear, as I also installed downpipes. -___________________________________________________________-
