Ignoring these components can result in more severe damage to the catalytic converter, ignition coils, and O2 sensors, leading to costly repairs.

Issues with Aftermarket Items: Incorrectly installed aftermarket components like alarms or exhaust systems can cause various problems, including draining the battery, triggering the check engine light, or preventing the vehicle from starting.
