If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer feasible when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause break to your catalytic converter and your 2018 Hyundai Sonata's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the right mixture of air and fuel that enters the cylinders in your engine. A combative O2 sensor can also cause a car to fail an emissions test.
• Your 2018 Hyundai Sonata has a vacuum leak. Every Hyundai Sonata has a vacuum system that performs a enormous variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine.

Over time, vacuum hoses can dry out and crack, highly if they’re exposed to curious heat or extreme furious.
• New Spark Plugs or Plug Wires are decisive for your 2018 Hyundai Sonata. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are combative or departed, you will experience scanty performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or break to ignition coils and O2 sensors, big to more expensive repairs.
