What is the reason for the Malibu XL not accelerating when stepping on the throttle?
2 Answers
If this situation occurs, there is no problem with acceleration at high speeds, but it may be accompanied by vibrations, indicating that the car lacks power and cannot increase speed. You can check components such as spark plugs. It could also be due to excessive wear of the rubber at the connection between the engine and the frame, which only requires inspection and replacement. The relevant introduction of the Malibu XL is as follows: 1. Introduction one: The 2019 535T CVT Ruixing version has a length, width, and height of 4933x1854x1472mm, with a wheelbase of 2829mm. The 2019 535T CVT Ruidong version has a length, width, and height of 4933x1854x1476mm, with a wheelbase of 2829mm. 2. Introduction two: The 2019 Redline 550T manual-automatic Ruidong version, the 2019 Redline 550T manual-automatic Ruilian version, and the 2019 Redline 550T manual-automatic Ruizhi version. These three models have a length, width, and height of 4933x1854x1473mm, with a wheelbase of 2829mm. The Malibu XL is the ninth-generation Malibu, born on the E2 platform with the internal code E2SC.
I've been driving for many years, and encountering the issue of the Malibu XL not accelerating when stepping on the gas pedal isn't the first time. The most common cause is a problem with the fuel system, such as insufficient fuel supply from the fuel pump or clogged fuel injectors. When stepping on the gas pedal, the engine doesn't get enough fuel, and the car loses power. A dirty air filter can also block the air intake, affecting acceleration. If there's an issue with the ignition system, like worn spark plugs or a faulty ignition coil, the engine misfires, and the throttle response becomes sluggish. Sensor failures are also common; for example, if the throttle position sensor malfunctions, the computer doesn't know how to adjust the throttle opening. Transmission problems shouldn't be ignored either, especially in automatic cars. If the clutch slips or gear shifts aren't smooth, the throttle response slows down. Safety first—this issue can become dangerous if left unchecked while driving. Quickly inspect wear-and-tear parts like spark plugs and filters, and if the problem persists, take it to a professional shop for diagnosis. Don't risk driving on the highway.
