What are the reasons for the Ford Escort's sluggish acceleration?

[LeTravis]

Ford Escort's sluggish acceleration can be attributed to carbon buildup issues, fuel system problems, and intake system problems. Carbon buildup issues: Including cylinder carbon buildup, throttle carbon buildup, intake pipe carbon buildup, etc. Fuel system: Adding incompatible fuel grades can lead to a decrease in the car's output power and reduced performance. Or, due to a blocked fuel tank vent, clogged fuel tank switch, fuel filter, or fuel line between the fuel tank and the carburetor, the required fuel supply cannot be met, resulting in a lean mixture and sluggish engine acceleration. Intake system: If the air filter is not cleaned in time after long-term use and becomes clogged, insufficient air volume can cause an overly rich combustible mixture. This leads to a decrease in engine power; for vehicles with turbochargers, once the turbocharging device fails, even if the throttle is applied, the engine will still feel sluggish and unable to perform.
