What Are the Symptoms of a Clogged Fuel Injector?

[DiAbigail]

Symptoms of a clogged fuel injector include: 1. Engine shaking; 2. Unstable idle; 3. Reduced car power and weakened performance, such as unresponsive throttle or uneven acceleration; 4. Increased engine noise; 5. A slight misfire sensation when upshifting at low RPM; 6. Increased fuel consumption; 7. Failed emissions test. Additional information about clogged fuel injectors: 1. Common causes of clogged fuel injectors include carbon deposits in the engine accumulating on the injectors or impurities in the gasoline blocking the injector pathways. 2. Gasoline naturally contains gums and impurities. Additionally, unstable components in gasoline can react at certain temperatures, forming sticky gum and resin-like substances. Combined with urban traffic congestion, where cars often operate at low speeds or idle, these deposits form and accumulate more rapidly.
