The car is in good running condition, but within the last two days it's been pinging and eating gas. I took the car into Nissan and the service man informed that my gas was running lean. In addition, he also mentioned a code P0345 which I found out is Camshaft Position Sensor and I replaced myself. The service also mentioned it could be a variety of issues concerning the fuel sytem and suggested I run another diagnostic for 300 dollars.
Does anyone have any suggestions as to how I can resolve this problem?
What is the $300 diagnostics? What is it supposed to do?
I would first get a OBD-II live data monitor and check your sensor data. Fuel is controlled by the ECU so maybe it's a sensor problem. Maybe the fuel lines/filter/injectors are clogged and you can check the fuel pressure.
