What if Mazda cx-5 has a tight throttle?

1. If the first accelerator is tight when driving, you can clean the accelerator.

2. The reasons leading to tight throttle are: dirty throttle; Throttle return spring; Throttle cable; Accelerator pedal; After the throttle line has been used for a long time, the lubrication degree of the metal line lubricating oil inside becomes sludge, and the resistance increases, resulting in the throttle pedal being too tight, which can be solved by replacing the throttle line.
