    Cap code probably from refueling while engine running.

    Ray, I would like to reiterate that the focus on this new camera, especially during close-ups, is extremely poor.

  4. Avataaar/Circle Created with python_avatars @mkernen says:

    You forgot to edit the part where you talked about the spring pressure. You have both the correct and incorrect spring direction explanations included.

  5. Avataaar/Circle Created with python_avatars @darrenglaser4742 says:

    Why must you always make the brake pedal depressed 😂

  6. Avataaar/Circle Created with python_avatars @timborden8121 says:

    Too many comments to be sure if it was said yet, but standard atmospheric PSI at sea level is 14.7 and I saw you had 14.1 with the PID so that's a bit of vacuum if you're actually at sea level. Not sure if that's the amount you should have at idle, but food for thought.

  7. Avataaar/Circle Created with python_avatars @cjservices8996 says:

    Like the diagnosis of it all

  8. Avataaar/Circle Created with python_avatars @dariocontreras4956 says:

    Like the longer videos more entertaining and educational

  9. Avataaar/Circle Created with python_avatars @David-ik8wj says:

    the tool thru a sensor code. Replace sensor! …….just kidding.

  10. Avataaar/Circle Created with python_avatars @fsurulz says:

    Ray I hope ur password 2 ur computer isn't 123😅

  11. Avataaar/Circle Created with python_avatars @CoolHandFlyer says:

    Ray, you are true honest mechanic. You take your time, diagnose the problems and issues, go an extra step to check safety, and then fix what NEEDS fixing. Not just up sell a bunch of parts for your bottom line. I salute you my friend!

  12. Avataaar/Circle Created with python_avatars @samsquires2877 says:

    The aftermarket radio with door chime sounds absolutely hideous in this thing. One of the reasons I will not put an aftermarket radio in a newer GM vehicle.

  13. Avataaar/Circle Created with python_avatars @jeggleston1651 says:

    The one time I don't see you change the Schrader valves, and the A/C system leaks! That's exactly why you previously stated that you replace them every time, isn't it?

  14. Avataaar/Circle Created with python_avatars @Wakeupandsniffthecoffee says:

    Ray, when you edit these, do you sit through the whole video?
    It seems like you would have to in order to make the various edits that you do.
    Considering how long your original video time is, it must be like living your life in real time and then in playback.
    I have a tough time sitting and watching my own videos. But I don't do much editing, except to combine a few clips into one.

  15. Avataaar/Circle Created with python_avatars @Wakeupandsniffthecoffee says:

    I would totally pay to have Ray give me some remote advice on my check engine condition with my Kia.

    Because I did the valve cover gaskets and am afraid that I may have an air leak, I even bought a smoke maching, after building one from an old halloween smoke machine. I haven't tried it out yet. The car runs pretty well, except at idle it may run rough.
    Even replaced both O2 sensors on one bank, the ithers are much harder to get to and I should have done it when the intake was off, but I didnt have these codes at that time, just oil leaks.

    I'm chuffed hearing your English accent

  18. Avataaar/Circle Created with python_avatars @mrs323 says:

    I wonder what Snap on’s diagnostic network thing would have said to do. Kinda wonder why all data doesn’t have a similar thing.

  19. Avataaar/Circle Created with python_avatars @ljerry8440 says:

    A great diagnostic vid for non tech/mech person.

  20. Avataaar/Circle Created with python_avatars @jaredd8473 says:

    I bet the driver valve cover was repalced because of the built in PCV valve in hopes on stopping the oil consumption.

  21. Avataaar/Circle Created with python_avatars @oliverullrich2168 says:

    I like how u go thru everything and not throw the parts bin at it

  22. Avataaar/Circle Created with python_avatars @Apismeliffera says:

    Another entertaining and educational video. Thank you. Just for fun, recorded you saying "Bump Stop". Now I can play it on WINAMP with it set to loop.

  23. Avataaar/Circle Created with python_avatars @tomwalton1188 says:

    Come on man, Ryobi tools are great for jobs around the house, just not industrial use. I love all my Ryobi tools and serve me well

  24. Avataaar/Circle Created with python_avatars @bodymaker16 says:

    silly noid 😀

  25. Avataaar/Circle Created with python_avatars @Jica says:

    I love the diagnostic videos more. Watching the process of finding out what is going wrong is fascinating.

  26. Avataaar/Circle Created with python_avatars @user-cw3kp9mc6q says:

    It probably needs blinker fluid

  27. Avataaar/Circle Created with python_avatars @brianbarnett6910 says:

    Don't know if you are aware of this, but I have been subscribed for a long time. I checked when I started watching this video and I had been unsubscribed.

  29. Avataaar/Circle Created with python_avatars @donpoelman6627 says:

    You're a great wordsmith, always entertaining & informative; keep up the great work Ray. Thank You!

  30. Avataaar/Circle Created with python_avatars @familieverhoeve7127 says:

    I think you should have changed the brake fluid…it is very old, full of water, not expensive, and much safer.

  31. Avataaar/Circle Created with python_avatars @dalejones3862 says:

    Ray checks everything and fixes what is needed to be fixed and goes it right

  32. Avataaar/Circle Created with python_avatars @CedroCron says:

    Thanks Ray! .. Enjoyed.

  33. Avataaar/Circle Created with python_avatars @BurkaLifter says:

    14.7 psi is one atmosphere at sea level and 59 degrees. maybe that is what the reading is?

  34. Avataaar/Circle Created with python_avatars @Drathorne81 says:

    Your ability to give in depth diagnosis is absolutely amazing. Don't stop! The ability to go from pulling engines to electrical gremlins is what makes you a genius in the world of car mechanics.

  35. Avataaar/Circle Created with python_avatars @BurkaLifter says:

    Step 3: Is it a PT Cruiser? Go to Step 4
    Step 4: Torch it

  36. Avataaar/Circle Created with python_avatars @sentinel7360 says:

    Ray does a very good job at articulating, explaining, and teaching everything he is doing on the car. Never feel left in the dark on the videos. I would love to see some more of these diag videos, keep up the good work

  37. Avataaar/Circle Created with python_avatars @glennsoucy4359 says:

    14.2 psi is normal atmospheric pressure at sea level

  38. Avataaar/Circle Created with python_avatars @michaelfrohn255 says:

    It’s GM, you may overload your scanner.

  39. Avataaar/Circle Created with python_avatars @Derick881 says:

    Only took 28 minutes on the video to finally check the actual brake booster vaccuum sensor and discover that it indeed was sending an implausible reading confirming what the scanner told you in the first 5 minutes.

  40. Avataaar/Circle Created with python_avatars @adrianstanton2652 says:

    The valve cover could be the oil consumption fix. Replace the cover with updated part. To prevent massive oil consumption.

    comment for the algorithm

  47. Avataaar/Circle Created with python_avatars @gregadams558 says:

    I guess it is 14.3 psi – 16 psi atmospheric pressure.

  48. Avataaar/Circle Created with python_avatars @stevelegion says:

    Hey Ray. Meant to say happy anniversary on your new shop. I believe you are about 13 months into your new shop. Love you bro. I hope you have continued success and prosperity

  49. Avataaar/Circle Created with python_avatars @joeymeyer3653 says:

    Mr. O did the most exactly same diagnosis and it was on a trail blazer also

  50. Avataaar/Circle Created with python_avatars @lescurtis7244 says:

    you just didn't do it right!! 😂🤣😂 operator eeeeerrrrrrr

  51. Avataaar/Circle Created with python_avatars @cascadesouthernmodeltrains7547 says:

    Driver’s side only valve cover… possibly trying to fix the PCV oil consumption issue. A 2010 shouldn’t have the issue, but someone thought it may.

  52. Avataaar/Circle Created with python_avatars @robertbuchalski6629 says:

    Yes nice diagnosis. Very informative. Makes you use you brain not just your hands.👌 best wishes bob

  53. Avataaar/Circle Created with python_avatars @davidballoid2118 says:

    Yup, Didn't see you change the Schrader Valves on the A/C fill/recovery lines like we always seen you do in the past, Lol 🤣!

  54. Avataaar/Circle Created with python_avatars @eduardoflores2510 says:

    Ray why don't you use the blue tooth OP Conn.

    All at sixes and sevens (being confused) dates back to Chaucer's Troilus and Cresida…

  56. Avataaar/Circle Created with python_avatars @Sir_Uncle_Ned says:

    There's no way the brake booster is at 70+ PSI when not even car tyres go anywhere close to that high. Absolutely amazing and thorough diagnostic.

  57. Avataaar/Circle Created with python_avatars @user-dv6om3hu7h says:

    Hi Ray it was very interesting.
    You have a Great day

  58. Avataaar/Circle Created with python_avatars @lokigames5091 says:

  63. Avataaar/Circle Created with python_avatars @kensiler9208 says:

    I didn't see you change the Schrader valves that you have said that you change every time. Did you forget, or have you changed your mind?

  64. Avataaar/Circle Created with python_avatars @cengeb says:

    Hose clamp pliers make it more better, right tools for the job at hand

  65. Avataaar/Circle Created with python_avatars @cengeb says:

    14.6 psi is atmosphere, so 14 might be right on

  66. Avataaar/Circle Created with python_avatars @davidclemdis4796 says:

    Yeah, too much diagnostics on this video did not care for this one, kind of boring for me. We’ll wait for the next one.😩

  72. Avataaar/Circle Created with python_avatars @cengeb says:

    they don't know brake fluid is supposed to be changed every few years, people are weird

  73. Avataaar/Circle Created with python_avatars @SubmarineSquid says:

    Good video. Thank you for not promoting incessantly your channel's merch. After Google forced us to join YouTube at $13.99 per month by blocking adblockers like UBlock Origin, it's disappointing to even see one commercial. Thanks again for not selling merch on the channel.

  74. Avataaar/Circle Created with python_avatars @WilliamLaakkonen says:

    You can also check for an engine idle change when pressing the brake pedal. If the engine idle changes when you pump the pedal, you have a vacuum leak.

  75. Avataaar/Circle Created with python_avatars @martylandry751 says:

    Awesome

    I love all your diagnostics. Some of this the normal DIYer can do. Thank you very much.

  81. Avataaar/Circle Created with python_avatars @dp2475 says:

    If the brake booster has a leak, wouldn't it trigger a lean code?

    Don’t forget to fire the parts cannon at the old crain-brainium; if it’s not working, all other diagnostic procedures will fail… epically! 😆
