The vacuum system regulates harmful emissions by directing the fumes as your car’s gasoline burns through the engine. If your car’s RPM is high in idle or randomly surges, then your car has a vacuum leak fault. Over time, vacuum hoses get weak and starts to crack if they’re have been exposed to extreme heat or speeding.

If you read on my previous article on how to replace the Mass Airflow Sensor, you can easily do this if it’s the reason for the check light. A faulty Chrysler 300 MAF can trigger this warning because it measures the amount of fuel your car needs to run the engine efficiently. It does this by measuring the air supply needed by your car’s engine. As part of the engine system, it regulates and adjusts changes in your engine like altitude. So, if you noticed your Chrysler 300 has issue starting, idling rough, or your throttle has shifted from usual state, this is a sign faulty MAF.

These sparks plugs are what causes the car pistons to move and helps the engine run. The spark plug is in charge of delivering spark from the ignition coil to the spark plugs. If these spark plugs are faulty or dead, you should replace them.

The aftermarket parts of your vehicle can drain the battery and even cause poor electric flow on your car. If you notice something like this in your car, consider taken it to a mechanic for proper adjusting and fixing.
  7. Your catalytic converter is bad or going bad. The catalytic converter is part of the car’s exhaust system. It functions by turning the carbon monoxide produced by the combustion process into carbon dioxide. If your catalytic converter is faulty and you don’t get it fixed sooner. Your vehicle will fail to pass emission test, indicate poor engine performance, and will cause your fuel to drain quicker. It will also cause you fuel economy.
  8. Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, referred as the O2 sensor is there to measure the oxygen received by your exhaust system. If the sensor is bad, your car will burn fuel faster and your car will have fuel economy issue. When you fail to replace a failed O2 sensor, it can affect your car’s fuel economy and also damage your Chrysler 300 catalytic converter and spark plugs.
