What to Do When One Fuel Injector is Faulty?
1 Answers
If a fuel injector is faulty, it should be disassembled for repair. If the damage is severe, it should be replaced. After replacement, the fuel injection pressure should be adjusted to 22-0.5Pa, ensuring good spray performance without dripping. Symptoms of a faulty engine fuel injector include the following: 1. Black smoke from the exhaust pipe. 2. Uneven operation of each cylinder, causing noticeable engine vibration. 3. Decreased engine power. 4. Weak vehicle performance. 5. To diagnose a faulty engine injector, let the engine idle and perform a fuel cut-off test on each cylinder sequentially.
