What are the reasons for the weak acceleration of Geely Vision?
3 Answers
Geely Vision's weak acceleration may be caused by insufficient power. Reasons for weak acceleration: Due to the blockage of the fuel tank cap vent, fuel tank switch, fuel filter, or the fuel line between the fuel tank and the carburetor, the required fuel supply cannot be met, resulting in an overly lean air-fuel mixture and weak engine performance. Long-term use of the air filter without timely cleaning can cause blockage, leading to insufficient air intake and an overly rich air-fuel mixture, which reduces engine power. Incorrect ignition timing or premature ignition can cause early combustion and detonation of the air-fuel mixture. Solutions: Check if the air filter is clogged and clean it if necessary. Check the throttle opening. When the accelerator pedal is fully pressed, the throttle should be fully open. Otherwise, adjust its cable or perform learning for the pedal position sensor and throttle position sensor. Check the high-voltage wires, spark plugs, and whether the high-voltage spark is too weak.
I previously drove a Geely Vision and also experienced lack of power during acceleration. That time on the highway, pressing the gas pedal felt like the engine was weak and sluggish. After inspection, it turned out the fuel injectors were clogged, probably due to using low-quality gasoline. Also, worn-out spark plugs can cause poor ignition and sluggish acceleration. Carbon buildup in the throttle body is another common issue - over time it can block air intake, preventing proper combustion. My advice: don't skimp on fuel quality, use reputable gas stations, and replace spark plugs every 20,000 km or so. Cleaning the throttle body is DIY-friendly - just remove the intake pipe and spray with cleaner. Letting these issues persist can hurt fuel efficiency, wasting gas and compromising safety. Get your car's ECU trouble codes checked promptly at a repair shop before minor issues become major problems.
Lack of acceleration is quite common in Geely Vision models, often related to the engine system. Fuel system issues like insufficient fuel pump pressure or clogged injectors can prevent proper gasoline delivery. Worn spark plugs or faulty ignition coils in the ignition system lead to incomplete combustion. Restricted airflow from a dirty air filter is also frequent - replacing it only costs a few dozen yuan. I've seen many cars with clogged catalytic converters causing exhaust backpressure and sluggish acceleration. Faulty ECU sensors sending incorrect signals can disrupt fuel control too. Start with simple checks: test fuel pressure and try replacing spark plugs first. If that doesn't work, visit a dealership to scan for ECU trouble codes. Avoid unnecessary part replacements - repair when possible to save money.
