Hi every one.
Well it is a long time since I had posted some Thread related to maintance.
The below mentioned Vitz Was suffering from the Heavy knock issue and Bad fuel Milage problem. As now a day's all of the JDM vehicle owner's are facing this problem each day.
Upon our diagnosis It was revealed that the Primary Oxygen sensor was faulty (There was no CEL ) But we diagnosed it upon brief analysis . So the Old One replaced with the new one and the problem is gone now.
Here I had to mention that many Local mechanic's and some other respected member's suggest to pour Hi-Octane to supperess that knock. But we did the Maintance and replace the culprit part's and the vehicle perform's on normal gasoline very well with improved Acceleration and with no knock at all load condition's..
Note: Without Analyzing the vehicle a normal person cannot judge whether which part is not working so alway's get your vehicle diagnosed properly and then go fo the major part's replacement.
For more brief info PM me. Thank's
