I'm experiencing a dead throttle after cruising for a couple of minutes at around 50mph. I'll try to accelerate and nothing happens. If I push the pedal to the floor, the trans will kick down and I'll accelerate. Also, when I experience the dead pedal, if I let up and then push the pedal, it will accelerate. I'm experiencing no codes but I think the apps (TPS) may be the culprit. Any suggestions?
