ФОРСУНКИ «УМЕРЛИ»: сервис потребовал 18 000 ₽ — я проверил их сам и нашёл ОБМАН

THE INJECTORS "DIED": THE SERVICE CLAIMED 18,000 ₽ — I CHECKED THEM MYSELF AND FOUND A SCAM The service claimed all four injectors were clogged and charged 18,000 rubles for replacement. But the P0302 error only indicated a misfire in cylinder 2, which doesn't prove the injectors needed replacing. I picked up the car, ran diagnostics myself, and checked the fuel system using an OBD scanner, a multimeter, a pressure gauge, and a mechanical stethoscope. The result was unexpected: the injectors weren't dead, just dirty. Instead of replacing them for 18,000 rubles, they required an ultrasonic cleaning and new O-rings. Spent: 1,350 rubles. Savings: 16,650 rubles. In this episode, we'll explore: — why the engine misfires and runs rough; — what the P0302 error code means; — how to distinguish a dirty injector from a faulty one; — how to check injectors with a multimeter; — why you should listen to the injectors with a stethoscope; — when ultrasonic cleaning helps; — when an injector really needs replacing; — why a service center suggests replacing all four at once; — how to avoid overpaying for unnecessary repairs; — how to protect injectors from re-contamination. Important: Injector specifications, acceptable resistance, fuel pressure, and removal procedures vary depending on the vehicle and engine. Before working, consult the technical documentation. The fuel system is under pressure, and gasoline is highly flammable.
