Acceleration issues

[stevew092984]

Hey guys, having trouble with my 3rd gen 3.4l V6 with acceleration. It’s taking much more time to accelerate to the speed limit, especially on the freeway. Just hit the 270k mark and didn’t routine maintenance. Oil, filter, drained the coolant and replenished with Toyota red, drained the ATF and replenished, changed the transmission filter, new spark plugs and NGK wires, checked PCV valve, cleaned the throttle body, cleaned the MAF sensor. Still need to clean the K&N air filter. Any ideas of what may be causing this before I seek out a mechanics help? Had one of the fuel injectors replaced a couple years back because it had failed and threw the check engine light. Maybe the others are starting to go as well? Haven’t had a check engine light illuminate yet though.
I appreciate it,
Thanks

Found the culprit! Throttle cable had a little slack in it from when I removed the throttle body to clean it. Tightened her up a bit and she seems to be running just fine now.
