How to Deal with High Fuel Consumption in Nissan Cefiro A33?

[DiAugust]

There are three main reasons for the high fuel consumption in Nissan Cefiro A33. The first reason could be carbon deposits in the engine, leading to insufficient power, delayed gear shifting, and increased fuel consumption. This is a relatively common issue, and the solution is to clean the carbon deposits in the intake, exhaust, and combustion systems. A simple cleaning can restore the car's fuel consumption to normal. The second reason is that the fuel supply learning value is too high. This is easy to handle—just disconnect the negative terminal of the battery for 30 seconds and then reconnect it. However, ensure that other learning values are not lost, as this could complicate the issue. The final reason is whether there is any dragging in the walking system or brake system. If this fault occurs, the solution is straightforward—take the car to a repair shop or a 4S store for maintenance.
