What causes sluggish acceleration?

Reduced acceleration is typically caused by restricted airflow, insufficient fuel delivery, weak ignition, or increased mechanical resistance. Issues such as vacuum leaks, exhaust blockages, old engine oil, or transmission problems all prevent the engine from producing power efficiently.

Can you use WD-40 to oil an air filter?

For those that don't know. Wd40 is NOT air filter oil. Your engine will perform better and last much longer with a properly serviced filter. Remember everyone, filter oil is cheaper than rebuilds.
