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 bad or old, you will experience poor 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 damage to ignition coils and O2 sensors, principal to more expensive repairs.

The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by neglected maintenance, which is why Bill Estes Toyota offers a complimentary multi-point inspection with every Toyota service.

If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less informed 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 damage to your catalytic converter and your 2019 Toyota 4Runner's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the polite mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or contrasting item can wreak havoc on your 2019 Toyota 4Runner if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prohibit the vehicle from starting.
