Misfire Cylinder#3 (Help!)

I'm agree with that. I had both 2nd generation and 3rd generation prius and the 2nd one is just better. The engine tends to break on 3rd generation way more often that on a second one. Usually a blowen head gasket at around 200k+ miles. I had 2009 prius for about two years, got it with 280k+ miles and after lots of driving ended up with 330k+ miles. Never had a problem with the engine (except an oil burning), not me, not the previous owner. Still going well with about 350k+ with a new owner.
