Ford Raptor has insufficient power and soft acceleration.

Reasons for insufficient engine power and weak acceleration 1. The lean-rich mixture leads to the insufficient thrust of the gas to the piston after ignition and explosion, which prolongs the combustion time and leads to the overheating of the engine. When judging the cause of lean oil, the acceleration is poor during operation, and it is improved when the oil pump is pulled by hand, but it is weak when the rich mixture is not used. At this time, we can say that the car is in a state of poor oil. There are many reasons for poor oil, which can be summarized as follows: (1) The adjustment of the main oil needle is too low; Oil level adjustment is too low; The main metering hole is partially blocked; Loose interface and air leakage; The air filter is not installed; The fuel switch of the fuel tank has poor oil supply. (2) The engine is poorly sealed; The crankshaft oil seal on one side of the engine fails and leaks oil; The joint surface of crankcase seam leaks air; The joint surface of crankcase and cylinder leaks air or the piston is assembled in the wrong direction. (3) Reason of engine reed valve: The reed valve is damaged; The rotary valve is installed backwards, causing back spray.
