    I have had way too many of those “zaps” from the distributor – now I will just go turn the engine off, make an adjustment, then start it again

    Geez you know the vehicle hasn’t been serviced “soon” when the bulb in the dash blows!

  16. Avataaar/Circle Created with python_avatars Efrain Garza says:

    From what I've seen your a trouble shooter and not a parts shooter! You replace parts per diagnostic conclusions and you verify your repair. As a tech myself , that's priceless and I commend your technical skills and wisdom.

  17. Avataaar/Circle Created with python_avatars Joe Wild says:

    Man you're the greatest you're very thorough my 96 Chevy pickup is running rough I've learned a lot thank you

    Your customers are getting a deal. My dad raised his marine rates to be equal to the average of local automotive shops he raised it to $124 from $94. Don't leave your retirement on the table .

    Auction Vehicles allways have problems. Its trying to avoid buying the ones with serious problems.

    You’re a good man Mr. O, , you’re out in the middle of east of BFE. Probably not the most affluent area, and all you’re trying to do is the best job possible and make the repair as affordable as possible for the client. I’ve only subbed about a year ago and have almost watched every video. Have spent many hours watching with complete total enjoyment. Rebuilt my first motor over 50 years ago, a 1967 Slant Six ha ha ha. Times have definitely changed……along with your $65 an hour ha ha ha

  38. Avataaar/Circle Created with python_avatars BamaDonDon04 says:

    The codes that keep popping up on mom say ECM and my truck is flawless we will keep resetting and turning the light off but the check engine light keeps coming on for some reason and I don't know why.

  39. Avataaar/Circle Created with python_avatars Stephen King says:

    The timing offset spec on those is + or – 2 degrees. You got it set perfectly within spec. Zero is the ideal, but -2 is still spec.

  40. Avataaar/Circle Created with python_avatars Anthony Farrell says:

    Don't understand why people switch off after 3 mins. Thank you so much for sharing your experience with us.
    Got my wife to sub just to hear that doorbell haha.

  42. Avataaar/Circle Created with python_avatars ScottysDetailing says:

    Love every one of your videos even the old ones. And the doorbell and the phone means you’re busy and people like you And you’re making money outside of you tube.

  43. Avataaar/Circle Created with python_avatars Zippo Varga Small Engine Medic says:

    I've had people unsubscribe for the same reasons. I say, good riddance to them, because when they stick around for the videos, I can always depend on them to be "Karen's" in comments. Often, I'll help them out and block them lol. Cheers! Zip~

  44. Avataaar/Circle Created with python_avatars Shane Harrison says:

    You get no complaints from me about that it's all part of the job

  45. Avataaar/Circle Created with python_avatars Shane Harrison says:

    Lol I can't imagine why he couldnt handle a little doorbell and phone action when I was working at Sears and quality auto transmission and a few other shops and the doorbell and phones rang constantly that the toll for doing business and it happens

  46. Avataaar/Circle Created with python_avatars CASTLEDOME KNIVES says:

    You can also swap o2 sensors to see if code jumps to other bank

  47. Avataaar/Circle Created with python_avatars Scott Farris says:

    Just j hi it the 2k subscriber mark! 😂 you hit about 100k per year average, Eric! Congratulations! You deserve it.

  48. Avataaar/Circle Created with python_avatars Doug Kubash says:

    Eric you probably remember before the OBD2 days on GM's, people would take the ck. engine bulb out . When they did that the ECM would not go into closed loop and I don't think you could read data. The better solution was a piece of electrical tape over the light. lol
