If your spark plugs or spark plug wires are bad or erstwhile, 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, large to more expensive repairs.

If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to exciting heat or extreme freezing.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, noted as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your car will be less accessible when it comes to fuel economy. So what happens if I don’t replace your O2 sensor?
