Hesitation acceleration

My mustang is hesitating sometimes when i accelerate (just feels like sticky throttle then it will pick up and go) and at other points it is fine. I already cleaned the TB and MAF and made sure there were no vacuum leaks or anything. Do you guys know of anything else that would cause this that i can check on?

Yes it's an automatic. I also just had the fuel filter changed. New plugs, wires too.

Check your fuel pressure.

Re: Hesitation acceleration

Check the fuel pressure and run a thing of throttle body cleaner through the gas tank or Cfoam time.
