Slow acceleration and does not rev up passed 2,500 RPMs

Scanned it and scan tool said it was a faulty shift solenoid A. So, I replaced both transmission solenoids and filter and now the vehicle shifts but still slow acceleration. I read that I should disconnect the battery for 30 minutes to rest the computer on the vehicle. So, I reconnected the battery and still had the same problem. Checked the wiring the throttle body position sensor and everything seems fine no cracks, cuts, or anything. I also checked the wiring to the pedal position sensor and also seems good removed the air box and noticed that the when the vehicle is off the throttle body opens normally when you step on the pedal, but when the vehicle is on the throttle body does not open at all. So, I removed the throttle body, gave it a good cleaning, reinstalled it, checked the wiring harness for corrosion, and everything looked good. I reconnected the harness, tried it again and still the same thing, it's like it's stuck in limp mode. Not sure what else to do or check. Any advice would be greatly appreciated. Thank you
