I am getting the code P0130 which indicates an O2 sensor 1 malfunction. This is the O2 sensor located before the CAT. The car does not run very well, and it is consuming more fuel. With the AC on, it barely moves, so I have to keep the AC off. My mechanic says O2 sensor 1 is bad. I am not too sure. He blames it on poor fuel quality caused while running the car on petrol without mixing hi-octane.
Although I try to fill up with hi-octane partially when I refuel. But these days hi-octane supply is very erratic and it is rarely available. If anyone has faced a similar problem do share your experience about how it can be fixed.
