Step-by-step explanation:
An ignition misfire or fuel mixture problem is an example of a Diagnostic Trouble Code (DTC) related to the engine performance. DTCs are codes stored in a vehicle's computer system that indicate a problem with a specific component or system.
For example, a P0300 DTC indicates a random or multiple cylinder misfire. This means that the engine is not firing properly in multiple cylinders, which can be caused by issues such as a lack of spark or fuel, faulty ignition coils, or clogged fuel injectors.
When a DTC related to engine performance is triggered, it is important to diagnose and address the underlying issue to ensure proper engine operation and prevent further damage.
