By 2006 150000km engine of the Prius runs permanently in the stand despite full HV battery, air conditioning, heating and light. Fan HV battery cleaned, was hardly dirty. All 28 batteries measured normal values. throttle flap wiped off really wide fat edge, clogged the air gap, the electronics regulated the dirt out. With fabric flap and spirit removed the noticeable fat edge. After that at next crossing error throttle flap hangs open, only electrically 5km reversed spring stop somewhat adjusted gap about, 0.6mm with actuator, learned anew. Now the motor goes out far too often?
