I’ve said it before and I’ll say it again. It is easy to head down the proverbial diagnostic rabbit trail. This video is just a reminder to all of you to try and not let that happen by planning the work and then working the plan. I am not exempt from these mistakes either. -Enjoy!

  1. Thats like my suburban. Guy i got it from said the intake gaskets needed replaced because of the misfire. I checked and it ended up being a bad ignition coil. Thats why you always stick to your routine.

  2. I just saw this one today, a year after you posted. Super nice as always BUT one question. I understand the shorted #1 injector but not sure I understand it’s effect on cyc 2&3 which were not shorted. Thanks

  3. But they're not embarrassed, after the $3K bill, or any other Pull A Part Til Its Fixed venture. And we're stuck cycling through Pull A Part Til Its Fixed garages, which has included dealerships.
    Right now, about all we have to discern is ASE.

  4. Sorry about your eye… that reminds me of a pirate talking to a barkeep:

    'Hey, I haven't seen you in a while. What happened? You look terrible.'

    'What do you mean?' said the pirate, 'I feel fine.'

    Bartender: What about the wooden leg? You didn't have that before.

    Pirate: Well, we were in a battle and I got hit with a cannon ball, but I'm fine now.
    Bartender: Well, ok, but what about that hook? What happened to your hand?
    Pirate: We were in another battle. I boarded a ship and got into a sword fight. My hand was cut off. I got fitted with a hook. I'm fine, really…

    Bartender: What about that eye patch?

    Pirate: Oh, one day we were at sea and a flock of birds flew over. I looked up and one of them pooped in my eye.
    Bartender: You're kidding, you lost an eye just from bird poop?

    Pirate: It was my first day with the hook.

  5. Using eyes (sorry eye) and ears first could tell a lot. Reading the spark plugs is essential in engine diagnostics. And how does the vehicle behave when driving can also tell a lot more than the codes.

  6. Installed a engine at 2 in the morning trying to get away from a nagging wife. Forgot to put the fly wheel on and didn’t notice until I tried to bolt it to the torque converter. Everything else was already hooked up 😡

  7. Awesome work as always Eric, I believe in safety third, i mostly get crap in my eye when it bounces off my face hits the safety glasses and back into my eye! Eric says.. "dont be a dope use that scope"!

  8. South main eye repair, you know about the “pulling your upper eyelid by the eyelash over the lower one trick” to getting something out of your eye? It might have saved you a trip to the shop, I mean ER

  9. So it was showing that bank running rich because the shorted injector was stuck open? And that caused the fuel trim to starve the other two cylinders of fuel? Or is it the other way around and the injector was stuck closed, causing the fuel trim to make the other two clinders rich enough to miss?

  10. Driving down the road, window down, whack. Right where my glasses are close to my cheek. In fact, i had a sensation that something may have gone between the eyeglass lens and my eye. WTH Cheek throbbing, keep driving, about 10 minutes later i look down between my seats and there is a WASP crawling around. It comes to life, and lucky for me flies to the passenger window. Pull off on the side of the highway, my turn to do the whacking. No smart ass comments— i am whacking the WASP.

  11. I'm a weekended warrior, i would love to have a pico, but can't justify the cost, as this is something i would use once or twice a year. Anyone got a recommendation to an affordable easy to use scope?

  12. Thank you for the video! Questions: How does the shorted #1 fuel injector cause other cylinders to misfire? But scan data shows #1 cylinder runs fine. How does the shorted #1 fuel injector cause the rear bank to run rich? Thank you very much!

  13. I have done a lot of work the same or similar to what you do. I have found flushing my eye/ eyes with a sink sprayer (with carefully adjusted pressure) to almost always solve the foreign object problem. The only time this wouldn't have worked was when I got a steel sliver in my eye (which of course argues for always wearing eye protection).

  14. Eyes scratch easy . Is there a way to figure out if my timing chain tensioner is going bad on a Toyota 2.5 the things chattering not sure if it's normal ?

  15. I'm always curious in your videos which flash light are you using. I noticed that you have plenty colors and shapes . I also use a different flash light in every car i work on 😂👍

  16. Yes Sir, stick to your guns, always confirm your "DIAG" it could be any thing, down to a simple broken wire, you never know what can be in that RABBIT HOLE 🕳!? ¿ 🤔 👀🐰, & you do want everybody to be happy Pappy…..

  17. So was the injector from the voltage reading shorted open? If reading voltage on the injector would not the key off sensors. relays and injector show anything?
    I am trying to understand if I do not have these tools and all I have it the mfgs key switch diagnostics, a meter and jump wires and I am stuck on the road or heaven forbid everyone goes out of business and need to rely on my noggin and skills I need to build on.
    I buy the older auto manuals that still have some manual test procedures, when diagnostic equipment was 5k to 10k on a crt screen.
    I understand you are an hour shop and need to understand the situation and provide the customer a solution in a timely manner. The diagnostic tools can make that process clearer with the data returns.
    Thanks for your time….
    So if those engines are failing on rings, is it the materials, the specs on how tight/loose they are or lubrication types?
