What is the cause of Kia ProCeed's sluggish acceleration?

I've noticed that my Kia ProCeed is not accelerating as smoothly as it used to. What could be causing this and how can I improve its performance?

One possible cause could be a clogged air filter. This can restrict the flow of air to the engine, resulting in slower acceleration. It's important to regularly check and replace your air filter to ensure optimal performance.

Another common issue could be dirty fuel injectors. Over time, these small components can become clogged with debris and affect the fuel flow to the engine. Consider getting your fuel injectors professionally cleaned to improve acceleration.

Have you checked your spark plugs? Worn or faulty spark plugs can cause poor acceleration. I recommend having them replaced every 30,000 miles to maintain the best performance.
