Oxygen Sensor on 6 cyl EF Falcon
Can anyone help with determining whether the oxygen sensor is OK? The car has a dual fuel system and I have a problem where the car hesitates on petrol when coasting, (it does the same on gas, but loses power intermittantly only on gas which feels like it is out of fuel)
You can correct the problem by releasing the foot off the throttle and then accelerating again. I have a simple 3 LED display - (red for rich, yellow for good, and green for lean) for checking the oxygen sensor, and when the problem occurs, all 3 LED's light up, indicating that the car is running rich, good and lean - all at the same time! When I release the throttle and again accelerate, the system goes back to normal ie. the test LED unit indicates that the car is running rich on acceleration, lean when de-accelerating etc. - ie. either one or 2 lights are on. Any help here is appreciated.
