The problem is that I already did an engine tune up at AS*ULanka. The fuel injectors were cleaned with their ultrasonic bath. Inserted a brand new VIC filter. They checked the spark plugs and said that they are in good order and that I can run at least another 20,000 Km with them. I asked the person in charge of the place subsequently whether an engine tune up also includes the cleaning of the O2 sensor. He said it does not. Also I have not checked the Mass Air Flow sensor. will do that too.

Can any member recommend a good place to get the sensor cleaning done professionally? Also the procedure that I am thinking of adopting is to clean the sensor and clear the previous data in relation to the O2 sensor so that the check engine light will go away. Run the vehicle thereafter to see if the check engine light comes back. Any advice?

Thank you for the advice.The unit at the current stage is not burnt, according to A*W people, but they said that it is heading that way. Did you do the cleaning as a precautionary measure? Or was there a problem and the cleaning fixed it?

I recently bought an AK-12, Nissan March Beetle and at the time of purchase there was no issue. Still one day when I accelerated quite a bit to overtake the check engine warning light came on, and it is still so. Thereafter went to my first visit to A*W Rajagiriya and a scanner was fixed to my car (Nissan Consult II) and the problem was zoned in as the malfunctioning of Oxygen Sensor B1. They recommend a replacement which is quite costly. I would like to know; 1) What is the role of the Oxygen sensor and whether it is very important to the day to day running of the car? 2) Whether cleaning the Oxygen sensor is a viable option? 3)If so what are places which specialize in cleaning sensors?, and 4) Whether there is a risk of corrupting the main software in charge of running the vehicle by plugging in scanners which are not original Nissan scanners?

Also just an addition to the topic although I pumped Rs.2500/= worth of petrol, the meter did not stop at exactly Rs.2500/=. It stopped at Rs.2501.--/=. Is that a cue that there has been some sort of cheating?

Yes, you are correct. I am also referring to the one near Roxy.

The three wheel parked behind obstructed my clear view of the meter, so that I had to jump over the slab containing the Petrol pump to get a clear view of the meter.

Well the above is hard and true words. I guess it is best to say how much petrol you want to pump when all the preliminary and necessary steps have been fulfilled.

I normally pump my petrol from two petrol stations in Mount Lavinia. Both are Ceypetc*'s no issue at all and sometimes I go to the IO*'s as well. Still one day I went to the Ceypetc* adjacent to the official road joining the marine drive at wellawatta (near the traffic lights). The guys pilfered Rs.500 from me. Now to the details. I never go to this Petrol Station, but unfortunately I went to this station on the fateful day as I wanted to check 95 octane on my vehicle.The petrol tank which consisted of 90 Octane was close to empty. So when I went there the guy pumping petrol was very friendly. Thereafter he informed me that the pump they were pumping 95 Octane.petrol was faulty. Already I had moved forward to the pump that was pumping 95 Octane and a three wheeler was parked behind me. So then I decided that the 90 Octane and 95 Octane experiment was best suited for another day. Got out of the car told the guy to pump Rs.2500 worth of fuel. He immediately started pumping as I could not see the meter resulting by the already parked three wheeler. By the time I had gotten to the meter he had already pumped more than Rs.2000. When I was trying to get close to looking at the meter he was saying "mahaththya langata enna, awith balanna". Thereafter when I started the vehicle I knew something was wrong as the tank meter was not full as normally would be, but I drove away as I could not prove his wrong doing. Now as I have the mileage I am going to go there and complain. Also I would like to be armed with information from other forum users as to; 1. What is the most correct procedure to adopt when pumping petrol to minimise the probability of getting duped?, and 2. What petrol stations are known for these wrong practices and best be avoided?

Also there is a less probability of sh*t particles hitting your bottom from spillages as it has to travel a longer distance.

Well guess we will have to wait for google voice navigation, Their maps are great. Still without the voice navigation intrinsic problems crop up, specially when you arrive at a junction as to which direction you must turn. Most of the time it is straightforward, but sometimes one will have to adopt a trial and error system. Furthermore driving only on navigation simply based on pure viewing is a definite distraction on Sri Lankan roads.

I would like to know whether voice navigation is available in Google Maps in relation to Sri Lanka?
