What are the symptoms of fuel injector failure?
3 Answers
Fuel injector failure has the following symptoms: 1. Black smoke from the exhaust pipe. 2. Uneven operation of each cylinder, causing noticeable engine vibration. 3. Significant decrease in engine power. 4. Weak vehicle performance. The solutions for fuel injector failure are as follows: 1. It is recommended to visit a 4S shop for disassembly and repair. 2. If severely damaged, the injector should be replaced. After replacement, the injection pressure should be adjusted to 22-0.5Pa, ensuring good spray performance without dripping. 3. Regularly clean the fuel filter to prevent excessive impurities from clogging the fuel injector.
I've encountered fuel injector issues several times. The car's engine keeps shaking when driving, like sitting on a massage chair, especially when idling at traffic lights - the whole cabin feels like it's wobbling. The throttle response is weak, acceleration is as slow as a crawling snail, and fuel consumption skyrockets, costing me over a hundred bucks extra per month. The exhaust pipe occasionally emits black smoke with a pungent smell, indicating incomplete fuel combustion. Cold starts failed multiple times, almost leaving me stranded at intersections. Later, the mechanic said this was caused by clogged or leaking fuel injectors leading to uneven fuel spray, and using some cleaning additives regularly could help.
As a seasoned driver with over a decade of experience, I'm all too familiar with the signs of fuel injector failure. The engine idle becomes jumpy and unstable, as if trembling, with sluggish acceleration response and no power when stepping on the gas. Fuel consumption noticeably increases, wasting a significant amount of money annually. Black smoke from the exhaust pipe or strong exhaust odors indicate emissions are definitely exceeding standards. Sometimes starting becomes difficult, requiring multiple ignition attempts. These minor faults accumulate and damage the vehicle's lifespan. I recommend regular fuel system inspections to avoid carbon buildup.
