If you are experiencing issues with your Mitsubishi Lancer, it could be due to a weak fuel pump or an issue with the airflow meter sensor. It is important to have it properly diagnosed by a mechanic rather than attempting to guess the issue and replace parts.
To diagnose a leak, you can use a fuel pressure gauge with an on/off valve. Connect the hose to the fuel rail side and close the valve when the engine is on. Then turn off the engine, and if the pressure drops, there is a leak on the fuel tank side. If the pressure stays the same, you may need to look for a bad fuel filter or fuel pump.
