What Causes the Lavida Engine to Lose Power and Shake During Acceleration?
2 Answers
Lavida engine power loss and shaking during acceleration are caused by carbon buildup. Reasons for carbon buildup: High gear, low RPM, and heavy engine load cause the governor to control the high-pressure pump to supply more fuel, while the intake air volume struggles to increase accordingly. Fuel burns with relatively insufficient oxygen, resulting in incomplete combustion of carbon, which leads to carbon deposits. Carbon buildup affects intake and exhaust, adheres to pistons and fuel injectors, impairing fuel atomization and further affecting combustion, creating a vicious cycle. Carbon cleaning treatment: Use cleaning fuel additives during daily driving to prevent carbon buildup. How to avoid carbon buildup: To prevent carbon deposits, ensure correct engine fuel supply and valve timing, and try to operate the engine under rated conditions, avoiding prolonged low-speed operation.
I've been driving a Volkswagen Lavida for over a decade, and it's quite common to encounter issues like sluggish acceleration and engine shaking. Most of the time, it's due to problems in the ignition system—worn-out spark plugs or excessive carbon buildup can cause misfires. The fuel system could also be the culprit, such as a weak fuel pump or a clogged filter, leading to insufficient fuel supply and poor performance. Restricted air intake, like a dirty throttle body, can also affect combustion efficiency. Ignoring these issues not only makes driving uncomfortable but can also lead to skyrocketing fuel consumption and potential engine damage. I recommend heading to a trusted auto shop for a computer diagnostic as soon as possible to avoid compromising travel safety. I've dealt with similar issues myself—cleaning the throttle body restored power instantly, making things much smoother.
