    OK, I really think I've fixed it. 4 successful round trips from the train station to the office. BTW, here is a pic of the fuel injectors I replaced. They go #1 through #4 going from left to right. You can see that the holes on the #1 and #2 are both open, and the #'s 3 and 4 both look like the holes are closed up or clogged. I'd say 378k miles is probably a little past a reasonable replacement interval. Prius Fuel Injectors with 375k miles.jpg

    That's what mine looked like also. I just scraped that brown scale off and put injector cleaner in the inline fuel filter I installed. Keep in mind that the car will not start running just the injector cleaner. After I tried to start it a number of times I took the fuel filter off and let gas from the tank flow to the injectors. The car started after gas got to the injectors. Of course I had to clear an error code P3191. This is the cruise control (failed to start code). My Prius hasn't had a P0301-P0304, or P0300 (cylinder 1-4 misfire and Random misfire) since.
