To rule out the Accelerator Pedal and Throttle Body (TPS)
Pull up Live Data - (KOEO) Key on engine off

Live Data:
The APP1 / APP2
TP1 / TP2

Slowly press the accelerator pedal down to the floor and slowly release it.
Ensure the PID readings remain steady and not glitching (jumping)
They should follow pedal movement and stay close to the readings, not jump out and then back.
Pay close attention to the (pedal position) for when you normally are experiencing the issue when driving, such as driving slowly through a parking lot (example)
and you can also try (Pausing) at spots and see if the PID remains steady.
You may try this with BOTH - Cold Engine and Hot Engine

As stated previously there are many factors than can trigger this code.
But these PID's are an easy visual look on how the APP / TPS sensors are electronically operating.
