poor engine performance

I wonder if anyone can help me to determine what's going on with my 07 taco. It feels like can't accelerate quick enough and it takes longer time to reach the 65mph. I replaced the spark plugs, the engine oil, the air filter, and still the same. Any suggestions?

Thank you so much.

Thank you for Pogiboy, Did you have your truck serviced at a dealer, or you did it yourself? I just don't want to be ripped knowing nothing about the costs.

Thank you.
