Hello Everyone. I've been snooping around this site for years. Thank you all so much for all the helpful tips and tricks you all post on here. I have a 2013 Prius V @ 120K miles. I already have had multiple misfire codes and a few rough starts in the mornings. I am looking to start a big project to rectify the issues. I already completed a spark plug and coil pack replacement by myself 2 years ago. Looking to do the EGR system/ intake manifold clean out and PCV replacement next week. I am now planning to change out the water pump and thermostat since I see that it is also a preventive recommendation. I do not drive her much now, but I will start a new job soon, which will put close to 80 miles a day on her. I live in SOCAL, so the climate is temperate, but it can be very hot at times. Anything else anyone can recommend I do while I have it all apart? Thank you all again. Leo
i think it could be an issue. you'd hate to go to all the work you outlined above, and then have to tear it all down again, but i'll defer to @Mendel Leisk and asrdogman above.
