I was really hoping for something a little more challenging but this one was pretty easy. Already had the camera rolling so I decided to put the video out even though it was just a coil. -Enjoy!

    Lots of help on different vehicle! Thanks man!

  2. Avataaar/Circle Created with python_avatars Majin says:

    Great video but it hurt my soul watching that car quest coil pack be installed denso all the way .

  3. Avataaar/Circle Created with python_avatars J C says:

    Thanks man, very informative and easy to follow. Like how you work on the truck like a common joe.

  4. Avataaar/Circle Created with python_avatars Pat Mowatt says:

    Got the exact same truck and swapped a coil in the fall. Started to get misfires on the #4 a couple weeks ago and immediately thought, well, there goes another coil- truck has 480 000 km on it, so not real surprising. Stuck the new coil in it, fired it up, still got the misfire. Since I had an extra set of wires from a scrapper, I just replaced the #4 wire, and boom, no misfire.

    I guess I should just check the easy fix first. But at least now I got a spare coil in the scrapper box.

    Great showing very helpful 👍👍

    are u located in Alberta?

    Good Job. Thanks for all you do, Eric.
    As an Engineer who spent years fixing and modifying Radios & Radars across Europe and the USA, I turned sales & marketer of high-end Test Equipment … I too "Almost failed High School". Now, having sorta-mastered a number of things, including Electronics & (of all things) Linguistics, allow me to say that even your "simple" fixes are helpful for us would-be DIYers. e.g. we get to see where things are and how you take them apart. Even your "Syntax" is helpful; it cements things into our memory banks. e.g. "Alright; we do have no spark" (as in: "Yes we have no bananas". ) I mean would could forget the absence of Spark? 😇
    Warm Regards to all,
    John in the NW

  8. Avataaar/Circle Created with python_avatars William Newman says:

    Not sure what coil is no explanation given. Assuming it’s something to do with spark plug. But video didn’t say what it for. Assuming too much for most followers. If you really want to do this right start with basics. Don’t assume anything.

  9. Avataaar/Circle Created with python_avatars J Ron says:

    Change Spark plugs?

  10. Avataaar/Circle Created with python_avatars David Rouse says:

    It'll be back Eric, That was a made in "China" coil. It Will Be Back. 😵

  11. Avataaar/Circle Created with python_avatars Bauke Sikma says:

    So why the coil failure? Have spark plugs been checked? High kv kills coils.

  12. Avataaar/Circle Created with python_avatars Something Else Here says:

    I used to do head gaskets on these when they were new. Suuuuper nice to work on. The first few months of production had a coolant leak issue and were recalled for it.

  13. Avataaar/Circle Created with python_avatars Steve says:

    If you can do it…I can do it. HAHAHA! Miracles can happen…I guess. HAHAHA!

  14. Avataaar/Circle Created with python_avatars Mike Whitman says:

    I have a question. Shouldn't you change the plugs and wire after changing a coil? This is what I was taught years ago. I know that sometimes coils fail, but to be on the safe side and not knowing what caused the failure, why not?

  15. Avataaar/Circle Created with python_avatars Szymon Krasuski says:

    Same engine as Lexus 450h?

  16. Avataaar/Circle Created with python_avatars griff Hall says:

    easy! great job and greater video E.O

  17. Avataaar/Circle Created with python_avatars Jimmy, Making it work says:

    “Easy peasy lemon squeezy,” as my shop teacher Mr. Longo used to say.

  18. Avataaar/Circle Created with python_avatars Scotty Parker says:

    I wish there were more mechanics like you,that are honest and tell the truth, makes me wish I live close by where I could get an honest diagnosis on my cars and honest repairs, thank you for being a stand-up guy I enjoy watching your videos, I'm not very tech savvy and the way you explained it makes it simple and understandable thank you for your good work thank you for your videos God bless you and your family

  19. Avataaar/Circle Created with python_avatars Jmasta7 says:

    Might also want to let this guy know that he doesn't have to put his trailer inspection sticker in the windshield looks weird as hell with 2 stickers

  20. Avataaar/Circle Created with python_avatars CD'S Automotive Garage says:

    Would you chnage the oil after this just to be on the safe side for raw fuel going to the pan an thinking the oil out an spining a bearing ? .

    I would but just curious what u thought

  21. Avataaar/Circle Created with python_avatars Hans gruber says:

    Nice work professor

  22. Avataaar/Circle Created with python_avatars wrenchhead525 says:

    I came really close to trying to sniff that spark plug boot!!! 😂😂😂 those boys are lucky to work with such a comedian!! 😜

  23. Avataaar/Circle Created with python_avatars Jam Ram says:

    These are not endless money pits – Scotty Kilmer 😲

  24. Avataaar/Circle Created with python_avatars mark holland says:

    Thanks

  25. Avataaar/Circle Created with python_avatars geoffrwelsh says:

    I missed where you inspected the plug to ensure it wasn't the root cause of the coil failure.

  26. Avataaar/Circle Created with python_avatars Doug H. in VA says:

    Coils are cheap and easy to install. You can get rebuilt injectors (send the old ones back for a refund credit) for very cheap and they are warranted and like new ones from an outfit in CA. Installing injectors means the fuel rail can drip some gasoline… so let a mobile mechanic do it. NO mistakes with any spark are tolerated.

  27. Avataaar/Circle Created with python_avatars Edwin Rosario says:

    Eric, I guess the customer just wanted a quick fix. Usually you would look at why the coil failed and one possibility would be you find out that the vehicle has a million miles and never had a tuneup. Wide open gapped spark plug. Hope that coil hold out. Love your videos. I’ve learned a lot. Thanks!

  28. Avataaar/Circle Created with python_avatars william williams says:

    good job i like that test light whats the part number for that tool??

  29. Avataaar/Circle Created with python_avatars richard fowler says:

    Wassup Dr. o

  31. Avataaar/Circle Created with python_avatars Paul Dionne says:

    Love all your videos Eric and this one was no exception. Your simple answers and diagnosis are important for all your viewers. That light bulb test is GREAT. When you want to know check out the SHOW. Sherlock (Mechanic of Auto) show.
    P.S. Car Quest is my place for parts. Have yet to receive a poor or wrong part price is always great to.

  32. Avataaar/Circle Created with python_avatars moorfan1 says:

    Eric, the very happiest of New Years to you and your whole family and crew of SMA. These videos are invaluable to me because they teach me so much about not only fixing vehicles but also how to be a great diagnostician in general!

  33. Avataaar/Circle Created with python_avatars num9908 says:

    People who are hating on Toyota for needing this repair are dumb. If this was a GM it would have needed a full rebuild! This thing looks older than god and it needed a $200 fix go cry in a corner with your chevy that will need new lifters and a cam shaft at 100k miles and it will cost you $5000.

  34. Avataaar/Circle Created with python_avatars Dave P. says:

    I cringed. Hard to see a Chinese part installed and not a Denso in a V6 Tacoma. 237k on my 1999 Tacoma. She’s my everyday driver less mid December through mid January when my neighbor insists he needs it for hunting.
