No Response to throttle pedal

[Lb7]

No check engine light comes on no codes batteries nice and hot. I can drive it as normal but after taking foot off of throttle pedal and coasting. I go to press the accelerator I have no response sometimes if I take my foot off the accelerator and try again it catches and we go again. But the last time I drove it 50 miles an hour was about best I got after it driving perfectly no check engine no codes no idea I've studied this issue several hours this weekend. I really could use some help. Thank you in advance

I’d say throttle body is the most likely culprit.

What are you using to scan for codes? - I ask because I've Learn'd the hard way that not all OBDII adapters and apps are capable - I use Forscan for that now.

 

You can also use Forscan to display live data, and view the throttle pedal position, throttle demand, and throttle position feedback, and this may shed light on what's wrong, but I'd start with scanning for codes with suitable equipment.
