Slow acceleration

Good morning.

First thing to check on low power complaints is the filters. Fuel and air are the most important.

Check the compression as well. low compression from a worn engine or timing would cause this.

Fuel pressure needs to be checked as well. not enough fuel will cause this issue.

Lastly, a clogged exhaust system will also cause this issue.
