Scotty,
I am attaching two image links that are captures by a BlueDriver scan tool from my 2012 Forester 2.5L automatic with 135k miles. Everything you see will be concerned with throttle position and accelerator pedal position. Do you think the numbers look normal? One image is with the throttle wide open the other image is with the throttle completely closed (it should be obvious which one you're looking at). I am experiencing what seems to be a lack of power in the higher rev range and I'm wondering if the throttle position sensor or possibly the accelerator pedal is going bad. No codes though. What is your opinion from looking at the images?

Nothing unusual. The computer will tell you if the accelerator pedal fails. Your problem lies elsewhere.
Do a standard tune up ...
change air filter, spark plugs, fuel filter (check pressure)
clean throttle body + MAF sensor
lastly run some injector cleaner
I've done all that except fuel filter. I'll do that next.
Then please say so next time. That way we don't waste each others time.
