My prius runs smoothly when it's cold and most of the time when it's warm. There are times when I pull over and go into a store and it's will run really rough for about 5 minutes of driving. The engine light comes on and gives a random misfire code. I took it into a mechanic and they found fuel in the number 1 and 4 cylinders. I had the injectors cleaned and inspected and the first time that I ran it and then stopped for 10 minutes it started misfiring again. The odd thing is that I can disconnect the spark plug wire on any cylinder and it will run fairly smooth. I'm confused!
have the same problem?
