Why does the Corolla feel sluggish and lack acceleration when refueling?

Corolla feeling sluggish and lacking acceleration may be due to a clogged catalytic converter. Below is an introduction about the Corolla: 1. Introduction to the Toyota Corolla: The Corolla is the tenth-generation straight-line upgrade of the Toyota COROLLA. Since its launch in November 2017, the Corolla has garnered attention from consumers worldwide. Now, this globally best-selling car is produced by FAW Toyota, allowing Chinese consumers to experience Toyota's latest technology and driving experience simultaneously. 2. Overview of the Toyota Corolla models: Its biggest advantage is low fuel consumption; it offers a comfortable ride with smooth driving; the interior is ergonomic with rich configurations. The main drawbacks include frequent issues such as burning oil, deviation, abnormal noises, and circuit problems. Recently, many users have reported problems mainly concentrated on the universal joint and in-car CD faults, questioning potential design flaws in components like the steering gear. Additionally, the brakes are somewhat soft.
When driving a Corolla, experiencing sluggish acceleration and a muffled engine is a problem I've pondered many times. It's most likely due to a fuel system issue, such as a clogged fuel filter causing poor fuel delivery or severely carbon-fouled fuel injectors leading to inaccurate spraying. It could also be an ignition system problem, with worn-out spark plugs or failing ignition coils directly affecting combustion efficiency. A dirty air filter restricts airflow, making the engine sound muffled. Another common cause lies in electronic control components, like a faulty throttle position sensor, resulting in delayed acceleration response. I recommend first checking the air filter and spark plugs yourself. If replacing them doesn't solve the issue, promptly visit a professional repair shop for a comprehensive diagnostic scan to avoid compromising driving safety and potentially saving on repair costs.
