The ICE in my 2004 Prius doesn’t seem to run all that well. I have a stoplight near my house that is almost always red. When I go out in the morning and wait at this stoplight I can feel the ICE hiccup several times before it eventually shuts off. AC and heater are off. This may be a problem when warm but I don’t know since the ICE tends to shut down before I come to a complete stop on all but the first few miles of driving. The hiccups feel like a milder version of the bump you feel when the ICE shuts down. They are not regular and eventually a hiccup seems to lead to ICE shutdown. Does anyone have any comments on this issue before I bring the car into the shop.
