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, major to more expensive repairs.

It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap?

If your check engine light turns on urgently after you put gas in your 2019 BMW 430i, first thing you should check is to make positive the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
