Some common symptoms of a bad fuel injector:
1. Engine misfires: If one or more fuel injectors are not delivering the proper amount of fuel, it can result in engine misfires.
2. Poor acceleration: A faulty fuel injector can disrupt the air-fuel mixture ratio required for efficient combustion and lead to a decrease in acceleration and overall performance of the vehicle.
3. Reduced fuel efficiency: When a fuel injector is malfunctioning, it may deliver an excessive amount of fuel to cause decreased fuel efficiency and increased consumption.
4. Engine stalling: A bad injector can cause an imbalance in the air-fuel mixture leading to engine stalling or difficulty starting the vehicle.
5. Increased emissions: A malfunctioning injector can disrupt the combustion process, resulting in higher levels of emissions such as CO and hydrocarbons (HC).
6. Rough running engine: The irregular flow of fuel caused by bad injectors may cause your engine to run unevenly with noticeable vibrations or shaking while idling or during acceleration.
