Why does my BMW 7 Series feel sluggish when accelerating?

I recently noticed that my BMW 7 Series is not as powerful as it used to be when I accelerate, is there something wrong with the engine or transmission?

It's possible that your engine may have a misfire, causing a decrease in power. Have you noticed any warning lights on your dashboard?

Another possibility could be a clogged air filter, which can restrict the amount of air flow to the engine. When was the last time you had your air filter replaced?

I would also suggest checking your fuel injectors, as they can become dirty and affect the performance of your engine. It's recommended to have them cleaned every 30,000 miles.
