    Million dollars question, don't you think? ( try Priuschat / google search)

    Did you try to troubleshoot by:
    - New spark plugs
    - New ignition coils
    - Cleaning / replacing fuel injectors, egr, egr pipe, egr cooler, intake manifold

    And still no luck?

    - Your diealership repair shop says - no solution, it's ok to drive bc no error codes..no big deal..

    I've found the root couse of the problem, will need some more time to 100% test and confirm . Stay tuned.

    So you know what the problem is and you won't tell us? How does that make sense?

    We're here to help people by sharing knowledge and experiences. You aren't doing that! Why not?

    What did you learn from your research? Or are you too important to share?

    As it says above I need more time to test under various driving condition. ( I've had this problem since 130K on my Prius, right now I'm at 190K and so far it looking promising) If it 100% fix., I'll post the update.
