O2 Sensor Misbehave

Suddenly feel some loss in power during night drive.

And it light up on the next day. Long time no see.

Power loss

Awful Fuel Consumption

Check Light

With this 3 symptom, without scanning for error code, Aron decide to change the o2 sensor.

Just notice that, the 1 I am using is slimmer...

Left: Slimmer, faulty 

Right: Thicker, bought from MML

At the same time, Aron change the driveshaft at the driver side and hope that the clicking sound during acceleration will go away.

But too bad, the clicking sound still remain, need to look into something else.

Check light gone though....Better fuel consumption now.
