I own a 2001 Prius (196k miles) which runs rough whenever the gas engine is off for more than 3 minutes, cold or warmed up. It runs rough for about 1 minutte than runs smooth.
My Toyota dealer has changes spark plugs and is now doing all sorts of diagnostics. They want me to okay a compression test (aprox $100) and replace the PCV valve (aprox another $100). They supposedly did a tune-up 2 weeks ago and did not find any issues except for the plugs. Check engine light is on, codes say multpile misfires.
Most of the problems started after Toyota did their 30,000 mile service a couple months ago.
Any guesses on what making it run rough?
