    I truly have to say, I'm an auto technician. I went to tech school back in 2009, just got into a dealership position about 3 years ago (a large gap of time where technology has truly picked up). What you Paul have done and continue to do as far as these videos with the classes, troubleshooting in the field, etc has been absolutely amazing to watch and learn from. You go so much deeper into diagnosing things, far more than anyone else who I have "picked brains" from in the field. I seriously cannot thank you enough for the amount of effort you put in for those like myself who want to truly become better. I am a big fan, I have subscribed and I will at some point soon be purchasing a copy of your works. You sir are awesome! Thank you!

      I absolutely agree with all your comments !!! As an experienced technician in New Zealand doing diagnostic work for over 10 years using scopes I always get a little something from your videos. Today was the coil turn on oscillations and what actually produced them work respect to the 2ndry ignition. GOLD!
      I recommend your channel to other mechanics all the time.
      Thanks for all the effort you put into fighting the good fight :)

    I was a ASE master tech from 1975 - 1985. I quit and started a remodeling/repair business for 35 years. I have continued to perform all my own repairs. Now I'm thinking of semi retiring and going back to working on cars part time. I have fully enjoyed all of your videos that will prep me to take my skills to greater levels. Thanks you for your time and effort to educate us.

    Hey man. I have my own automotive shop and I also build racing engines and racecars. I've never had a teacher for the auto world though. Even though over the years I've read alot of ASE books. But people have no clue what it takes to figure things out sometimes. I've watched alot of your vids and I am subbed. Thanks for posting and teaching this young generation

      ScannerDanner no prob. I attended courses at The School of Automotive Machinists (Sam Racing) in Houston Texas. One of the best engine builders in the world. So I learned to build and machine and study race engine theory. But over the past 10 yrs I have gotten alot of general Auto stuff. Alot of times it way more difficult to diagnose and figure out what's going on. But anyway I have a snap on Solus that I use and that's how I found you a couple years ago. You teach a difficult occupation very well sir. I may pick up your premium before long.

    Amazingly informative presentation. Thank you so much! At 58 years old I still find this fascinating. I spent a couple thousand on a nice Pico rig about 20+ years ago and it's amazing how much you can learn just from diving in. I've been out of the professional auto repair business for 35 years but still do a lot of my own work. Unfortunately my rig was stolen years ago but watching this has kind of reignighted my curiosity. I may have to get another Pico to keep me out of trouble 😉. Danner, great job, thank you.

    Case in point, I had a P0301. Cylinder 6 and 7 had no compression.
    Also, misfires aren't the only thing that can cause misfire codes.
    Misfire monitors, in my opinion, can only be trusted to tell you that the crankshaft slowed down. Bad ujoints, bad engine mounts etc can cause the crankshaft to slow down and can cause misfire codes. I've seen it myself.

Your videos are a type of ministry in that you not only bless techs with education , you also help many people with fixing their transportation to keep their jobs, get their children to school and the doctor and have a way to church to worship . You have a gift in teaching a difficult topic in a clear yet detailed way . No words can say thank you enough my brother in Christ . A million thumbs up to you .

    @scannerdanner I have a capacitive pickup that is very similar to the one you use. I use it with my verus and a small handheld similar to this one. It will not show nearly as much detail with the spark event as the ones I have seen you use. Connections are correct. Do you think it is just because it may be a cheap knockoff? Thanks, justin

    Mr Danner, good afternoon.
    how to diagnose misfire caused by spark plug gap? how to determine the correct spark plug gap when there is no possibility to change coil charging time, or any other parameter of the ignition system? Thanks in advance.

    • @ScannerDanner

      Firing line is not just compression but is affected by it. And no, you need a scope to see this stuff. Thanks for watching!

    Dan is it possible to detect misfires on control O2 sensors values alone? For example, we have a wideband probe precat and narrowband postcat for control. If the control probe is periodically hitting really low numbers (like 0.1V), can this be an indication of a misfire, too? Let's say the manifold and the exhaust is absolutely leakproof...

    • @ScannerDanner
      @ScannerDanner  2 ปีที่แล้ว

      Scan data O2 values can be used as a guide, but alone? No.
      You can scope an O2 signal and then sync off of an ignition firing event and use that to find the offending cylinder, but this test is very difficult to do and interpret

    • @seasonedtoker
      @seasonedtoker 2 ปีที่แล้ว

      @@ScannerDanner thanks! It is actually a case, where ECU is not the best at reporting and detecting intermittent misfires becausenit constantly wanta to equalize cylinders inside the bank (it is a Bosch unit that reports a cylinder rough running parameter), it constantly reports faulty pte cats and post cats, cat efficiency... All that has been replaced twice, checked for air leaks and exhaust leaks... It always reports control probes ageing even when new. And I can see them drop really low, then normalize without the precats even reacting to that drop.

    hello there.....I have a buick lesabre 1995 that has the same engine 3800 in my car and I am dealing with 2 misfire.....The number 4 cylinder ignition coil isn't firing at all and cylinder number 2 will sort of spark but not like consist like the rest of the ignition coils......First I tried swapping coils around but the problem didn't move at.....the coil that I thought it was bad (after switching them around) was good so my next step is the ignition coil module system.....After putting a new ignition coil control module in it I am still stuck with the same misfire.....I even put new spark plugs wires in it (since I change the spark plugs last year and forgot to get new plug wires) nothing change at all.....I even bought new ignition coil pack all three of them and the problem is still the same........I wanna know whats my next step to pin point the causes of 2 misfire that I'm trying to fix......thanks..... love your videos keep up the good work brother.

    I have a wrangler 2012 3.6 v6 with diagnostic codes P0201 P0202 P0203 P0204 P0205 P0206 all six injectors circuit open active.
    I only replaced the oil cooler and it was running perfect before the job.
    Now it is miss fire counter injector 1 and 2.
    I scoped the ecu pin 8 and 9 C2 connector and 8 was clean but 2 was messy.
    Any ideas as to where to look. I have repaired some open wiring from previous guy working on it.
    Thanks

    I can't figure out why some of the DIS ignition systems' waveform(s) look that way . Low firing lines falling that way

    time :34.29 its actually back emf that your seeing as on oscillation rather than reserve energy its actually wasted energy as it is not big enough to produce another spark

  • @murlecampbell8360
    @murlecampbell8360 7 ปีที่แล้ว

    Paul, How MUCH of a straight up line constitutes a bad ramp waveform. Just missing occilations or to what hieght of a straight up line is considered "bad", or ANY form of a straight up line?

    • @ScannerDanner
      @ScannerDanner  7 ปีที่แล้ว

      lot's of variables on coil ramps. Some systems you cannot even see the turn on oscillations. In general, no straight up lines on anything that is creating a magnetic field. But you also need to consider the waveform characteristics on the other coils. The ones that are working properly
