05 taco V6 accleration issue

Hey guys last week I noticed after leaving work that my taco had trouble accelerating. It felt like I was towing a trailer till i got to about 25 then it took off like normal. After looking on the forums i cleaned out my throttle body and MAF sensor. Ran great after that and drove it 6 hours to a wedding the next day. No issues on the trip. This morning on my way to work it started doing that again. Was thinking about replacing o2 sensors as they are getting old anyway but i dont think that the issue. Anyone else have this problem?

 

Posting mileage may help. Plugged converter? Bad plugs? Clogged air filter? Any CEL? E brake cables failing and dragging? Have you run a scan? Many places like Advance Auto will scan you for free.
