What Causes Lack of Power in BMW 528 Acceleration?

[Flores]

BMW 528 acceleration may lack power due to severe carbon buildup or excessively dirty transmission fluid. Severe Carbon Buildup: Carbon deposits on the throttle body can affect air intake, deposits on the spark plugs can affect ignition, and deposits on the fuel injectors can affect fuel injection. Overheated carbon deposits can also cause pre-ignition, resulting in weak vehicle acceleration. Excessively Dirty Transmission Fluid: Transmission fluid that is too dirty or insufficient can also lead to weak vehicle acceleration. For automatic transmissions, the transmission fluid not only serves as a lubricant but also acts as the medium for hydraulic mechanisms. These hydraulic mechanisms control the clutch and shifting systems. If the fluid is too dirty or insufficient, it can cause these components to malfunction.
