A lot of things affect a car's perfomance. But for ex-Jap vehicles, the most common fault is a worn out fuel pump or pump housing. Common signs will include : Flat-footing your accelerator with little to no response. Your car cuts off at robots/intersections when you slow down. Difficulty in starting especially in the morning. Noticeably higher… More fuel consumption. Rough/ uneven motion whilst driving.
