What are the effects of insufficient power in the car?

Hello, the main reasons here are as follows: First, the fuel pressure is too low, resulting in insufficient oil supply and insufficient power. It is recommended to clean the injector and check the oil pressure at the same time. Second, poor ignition leads to poor combustion and obvious fuel waste. I suggest you replace the spark plug. Third, the cylinder pressure is insufficient. This common situation is that the cylinder is missing and shivering, which will also lead to insufficient power. It is necessary to measure the cylinder pressure. Fourth, the engine throttle is too dirty to clean, and the exhaust three-way catalyst is easy to fail. I suggest you go to the repair shop for a comprehensive inspection. I hope my answer can help you. Have a nice trip. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
