Preventive maintenance (engine does not stop)
To reduce the risk of your car breaking down immediately after starting, regular preventative maintenance should be done. You can do the following:
1) Check the fuel system – Make sure the fuel filter, fuel pump and injectors are clean and working properly. Replacing the fuel filter regularly will help prevent clogs and ensure proper fuel delivery.
2) Check the ignition system – look for the spark plugs, coils and distributor cap (if your car has one). Replace as directed in the owner’s manual or if you notice wear.
3) Monitoring the intake system – The Idle Air Control Valve (IAC) and Mass Air Flow Sensor (MAF) play an important role in controlling the air-fuel mixture. Keep these parts clean and replace as necessary to prevent problems.
4) Check the timing belt or chain – A slipping timing belt or chain can cause the engine (and other things) to slip. Inspect regularly for wear and replace as needed or where recommended by the manufacturer.
5) Check for vacuum leaks – A leak in the vacuum system will stop the engine. Hoses and connectors should be carefully inspected for signs of wear or damage.
6) Keep up with ECU updates – Update your ECU software whenever manufacturers release updates to improve engine performance and fix potential problems.
7) Test your battery and charging system – Make sure your battery is good because a weak battery can cause starting problems. Also, make sure your charger still has a battery.
