What are the reasons for the weak acceleration of Chery Tiggo 3x?
2 Answers
Introduction to the reasons for the weak acceleration of Chery Tiggo 3X: Carbon deposits: Carbon deposits on the valves, idle speed motor, intake tract, combustion chamber, and spark plugs may cause engine stalling during idling. Driving in congested roads: Frequent acceleration and deceleration alternation when driving in congested roads for a long time may lead to weak acceleration when driving again. Poor fuel quality: The use of poor-quality gasoline will affect the gasoline filter and fuel line, which may lead to poor fuel supply and thus weak acceleration; it will also affect the service life of the three-way catalytic converter in the exhaust system. If the three-way catalytic converter is blocked, it will directly affect the acceleration performance of the vehicle, and also lead to increased fuel consumption, resulting in the phenomenon of weak acceleration.
I've been driving a Chery Tiggo 3x recently, and the acceleration feels particularly sluggish, like there's no response when stepping on the gas pedal. This issue is quite common and is generally related to the engine. There might be a problem with the ignition system—either the spark plugs are worn out, the ignition timing is off, or the ignition coil is faulty, leading to incomplete fuel combustion and a lack of power. Another possibility is a fuel system issue; if the fuel pump pressure is insufficient or the filter is clogged, fuel can't be injected properly, resulting in slow acceleration. Don’t overlook the intake side either—if the air filter is too dirty or the throttle body has severe carbon buildup, airflow is restricted, starving the engine and causing sluggish performance. Sensors, like the air-fuel ratio sensor, could also be faulty, affecting combustion efficiency. Last time I took it to the dealership, they found it was indeed due to the air filter and fuel system issues. After repairs, it improved significantly. I’d recommend getting it checked soon—don’t wait until you stall on the road. Safety first! Regular maintenance, like cleaning the intake system, can help prevent this issue.
