Come along with Eric O. at the SMA shop and let's have a look at this 2013 Dodge Grand Caravan 3.6 liter that was bounced around between shops and ended up at ours with a poor running / misfire complaint and a code P2308 "Ignition Coil 3 Secondary Circuit - Insufficient Ionization" and see if we can diagnose it.

    look at the condition of this car, the van was in 2 shops( now 3), and they didn't care, that's why i try to learn and repair my own cars, i believe a lot of the time car goes to shop( some of them) and comes out worse.

  23. Avataaar/Circle Created with python_avatars John Doe says:

    Cheers for the awesome videos SMA!
    Yeah can be depressing how some people treat things. I bought a WR450 for a trail thrasher. Out of habit I went to change all fluids… and found over half a dozen destroyed threads so far. Little tiny 7 ft lb m6 bolts going into soft alloy that have been swung on and come out with lots of alloy shaved threads. Helicoil time! ;p

  29. Avataaar/Circle Created with python_avatars Dr Kar says:

    Interesting to watch the diagnosis/detective work

  30. Avataaar/Circle Created with python_avatars zakura ayame says:

    The Emperor's new air filter. Better flow than K&N and protects just as well without the risk of the filter oil fouling your MAF sensor!

  31. Avataaar/Circle Created with python_avatars Mark Wheeler says:

    I assume the other shop still gets paid for all the damage they did. Ridiculous!

  32. Avataaar/Circle Created with python_avatars Garth Clark says:

    I'd have to agree on the poor workmanship mannerisms of many repair shops. My vehicles have lots of plastic interior and exterior locations as well as mechanical and from past experiences, they break the little locking tabs on every connection they touch, crack plastic parts where there is a fastener securing them down due to over tightening them and simply general man handling brittle parts that are very difficult to replace and simply say "Well they're old and brittle, we can't do nuthin about that". Well guess what? It didn't come into your shop that way so, you can replace everything you damaged. They have no etticut what so ever. You'd think they would get the impression a very clean car under the hood etc. would be a joy to work on but no, they rumble through the vehicle as if it were out of the junk yard. They are about as useful as RATS eating away on your car parts.

    As James Rolfe would say:

    The car runs like AAAASSSSSSSSSSSSSSSS!!!

    Torque converter Problem

  36. Avataaar/Circle Created with python_avatars Steve Jones says:

    Man whatever you do don’t buy a Chrysler

  37. Avataaar/Circle Created with python_avatars beulahboi says:

    I like your videos a lot. I'm really scared tho. I really care about my car, it's kind of my pride and joy. I need a good mechanic. What you show on video really makes me nervous. The guy I used to use, forgot to secure a wheel on my sister's car and acted like it was "no big deal" so I'm on the hunt for a new shop. Accidents happen but they way it was handled was also unacceptable. Now I'm worried about taking my car in and it ends up hacked to pieces. I wish you weren't 4.5 hours away, man.

  38. Avataaar/Circle Created with python_avatars Jordan Grey says:

    I have a question.. If I buy a PCM with the same part number will it still need to be programmed because of the vin number?
    And also I found one at the auto wrecker but it was off of a Chrysler 300 3.6L. Will that also work???

  39. Avataaar/Circle Created with python_avatars King Of Sync says:

    No air filter and no oil cap either.

  40. Avataaar/Circle Created with python_avatars Brian Eckert says:

    Another reason why I wish you were close to us. Hate part swappers…

  41. Avataaar/Circle Created with python_avatars Cuba's Automotive says:

    Reviewing old videos… this was great. I like your process. KISS.

  42. Avataaar/Circle Created with python_avatars BlueDrive Diagnostics says:

    The story about the other shops. When all else fails, they turn to the good mechanic/technician.

  43. Avataaar/Circle Created with python_avatars Phil Jerome says:

    Mongo break!

  44. Avataaar/Circle Created with python_avatars paul munoz says:

  45. Avataaar/Circle Created with python_avatars a&s construction says:

    Would welding ground it to the wrong spot cause electronics computer go bad as far as shorting it out

  46. Avataaar/Circle Created with python_avatars Xxlovely_ nnightmarenightxX says:

    can you not switch the Eeprom to keep the proper vin to match the vehicle. That is what we did in the old days.

  47. Avataaar/Circle Created with python_avatars Kurt Bargmeyer says:

    I’m just wondering where do you get the wiring diagrams from. Does it cost money.
