Car feels sluggish

Hello,

Low power output can be several contributing factors.
It could be as simple as a clogged air filter, which will restrict airflow into the engine and that will lead to sluggish acceleration.
This can be also due to worn mas air flow sensor or a weak fuel pump.
Having a plugged catalytic converter can also cause slugging power.

Here is a helpful guide that covers the typical lower power reasons:

Many times, engine tune up can help restore the performance. Like changing the air filter, fuel filter, plugs, clean out throttle body etc.

Please let me know of any questions.
Thank you.
