I prefer these types of videos. It's the real deal, no pre-arrangements just, "This sucker doesn't work right and I've got to figure out how to fix it." That's real life. Good stuff.
Right right right I am a lifer
Yes, you learn more this way and makes the video more fun to watch.

I am an old mechanic from waaaay back and really envy your patience and tenacity. Not changing parts before knowing for sure what is the CAUSE. You are a fine example for your peers and those who in the future. Much ablige:):):):).
Thanks brother!
I get bitched at, at the shop sometimes for doing the "check every possibility" methodology you teach due to time, however, when no one else can figure it after throwing parts at it, it becomes my head ache and i get it every time. So thanks for what you do i have learned alot. Thinking outside the box, and approaching things from a different angle. Also, i am a devout "sccpe guy", i diagnose plugged cats with an in cylinder transducer doing running compression tests, home built transducer set up with tons of home made attachments. 15 years in the shop, and your vids inspired me to "up my game" by learning the scope about 3 or 4 years ago. Now its the first tool i grab for diagnostics, if i can figure out a way to do it.
Rod X 1!!
I've had cars that don't start and all it was is a loose fuse,or wire disconnected
@@ScannerDanner hey man I have a serious question if you can help me with 91 F-150 5.0 manual 2wd randomly between weeks months to years I don't know randomly the truck will fail the ECM brought burn it up destroy burn up ignition module on the side of the distributor burn it destroy or it will rarely get the coil do you have any suggestions to what I can start looking forward to try to fix this problem for good can you give me a general direction like look at the ignition module wires or the engine harness wire pin number maybe this could help ground on driver side under radiator I'm just saying anything this is my only vehicle man and it's going on two to three weeks being down and it is starting to really hurt my wallet and put me a very bad position so thanks for anyone anything plz
thumbs up for crawling back under for the 02 reading :)
we need more people like you in the world!!!!!! wish you were my automotive teacher
He is an automotive instructor
In some ways older vehicles can be harder to diagnose than newer ones. As you said, it is a lost art. There's nothing quite like the feeling of getting a "vintage" vehicle back on its feet, when most of its brothers are long gone to the junkyard in the sky :)
All that said I Rather have an older vehicle You don't have to take half the vehicle apart to get What Your after And you don't have to buy ten thousand dollars scanner either
You are a TRUE Tech. There are so many parts changers who think they know what they are doing. But don't know if their butt is bored or punched. Thank You!!
Kenneth Shilts thanks Kenneth!
Paul,you're the real deal,genuine,nothing fake in your videos. Love that!
Mr. Danner, you are an amazing auto technician. Sure wish I had you for a teacher in trade school. Thanks for all the great vids.
Great video! We all appreciate all the sacrifices you make to bring us such great video content. I really like the "field" videos the most. I've been mechanic 13 years and learn a lot from you and your brother
Hi Paul, I found your channel a few month ago and watched your all videos but still watching your both channels every day.
I learned a lot from you. Thank you very much
I learned a lot from this, I especially like how you verified o2 circuit integrity. Great work, Thanks Paul.
I like the way you explain your attitude toward customer expectation vs reality and charging out for your time, especially with vehicles that have multiple issues.
I also like the way you emphasise road tests before and after repair, it can be difficult, especially when pressured for time.
Really enjoying your videos on this and your premium channel, time and money well invested IMO.
Keep up the good work Paul, you are an inspiration to your viewers.
Doc...
1988 ford f150 here! Just wanted to say without this video I'd be bigtime screwed. Was able to chase down and rule out many factors in my truck. You sir are awesome and very knowledgeable . Ty ty ty
Awesome
that was great.watching you change direction and going beyond the egr valve and testing the o2 sensor with the test light was really fun.thanks for the after shot on the o2 sensor because little things like that make your videos better than others.people say old school cars are easier to work on but data from computers really helps for direction.that was great troubleshooting.
I am a retired auto mechanic from long ago. It’s nice to see a real video from a real mechanic. I just replaced (sucked in) throttle body gasket and cleaned all the crap out of the inside of the throttlebody that fixed my problem. Oh I changed o2 when I did the starter. Thanks!
Great video as always Paul! I really like these videos were we can see you in action and that you don´t leave anything out! Have a nice weekend!
New owner of 1990 f150 with pretty much all the same issues thanks for the real world diagnosis!
The best padding for under car work that I have found is a piece of thick carpet. You can get these at any carpet store, in almost any size, for very little money. Just keep it rolled up and laying in the back of your truck. It insulates from the ground well, even on snow. Just get a THICK one.
Also, for a "headrest", the boat seat cushions that are about 15 inches square work well. They are about 3 inches thick, and have flexible "throw handles" on two sides. Cost is about 15 dollars at any outdoors store.
Also, one of the blue utility tarps available at any tool shop or outdoors store can be very useful for keeping the carpet dry.
Working underneath a car in cold weather is tough enough, but if you can find ways to stay very dry and not have to feel all the rocks and ice on the ground makes a big difference. And Paul, you might try wearing a cap (you know, a winter cap, not a baseball cap)!
Hang in there.....
Paul, thank you for the things that you do , that you don't have to do but you still do it . I really appreciate it.
When I was in auto school they taught me how to time those, now that makes me feel old, hopefully though this will give the younger techs and diys and idea on what we were working on back then. Also made me think about when I fixed up a 89 crown vic for my brother that had a egr pos code. It was a bad pos sensor, and it made me go through the same process on my old snap on brick,lol. Nice job Paul.
I just can't believe how good and honest you are. Don't ever change. Good people will see it even when u think no one is looking.
God bless you my friend for those encouraging words. I truly appreciate it.
Another great video. Thanks. Working on those old rigs sure make OBD2 a dream.
Paul - YOU are a SUPER TECHNICIAN AND INSTRUCTOR. I do know that you can properly diagnose and repair any vehicle . I am 100 % sure that you have forgot more technical info than I even know and one of your greatest traits is you are honest and able to admit if you have overlooked some needed test or possibly missed something. That being said , there is NO DOUBT , you WILL ALWAYS find the problem. MANY , MANY THANKS for ALL the LIVE troubleshooting video's you post. 😊😊👍👍👍👍👍✌️✌️✌️✌️✌️✌️🧐
Thank you so much my friend
Ur system approach is very good.one of the best techs in the business
Actually we could get data from the sensors,but not from the self test connector. The EEIV monitor hooked directly into the 60 pin ecm. It is like a break out box with a LED display. So it was live unprocessed data with a knob that rotated to view different sensors. Great video Paul, it brought back a lot of memories!
Excellent. I really appreciate how you explained your thought process through everything as you went.
It’s nice to see someone that that really loves his job
thanks for taking the time to show a known good 02 sensor on a pre obd2 system.
WE DO APPRECIATE WHAT YOU DO FOR THIS INDUSTRY GOOD JOB
Thank you for sharing your knowledge with us again Zen Master !
I know this is one of your older videos man. But wanted to say that once again, you are teaching me a lot about a vehicle i buy to fix up. I know almost nothing about fords and currently have it tore apart. Removing smog and egr systems, new gaskets etc etc. Thanks a ton.
I have a bunch of EECIV videos for you! Glad you found me. I can help too
Any time you see a deep notch in a crank pulley that is used for a magnet pick up style timing probe. If you had an old snap-on counsler II they use to have the probe adapter. But who has one of those old dinosaurs.Oh wait I do haha

Hahaha It’s weird seeing your comment on here from 4 years ago ........ look at you now
You two guys are the shizzz
Scanner Danner, Eric O = GOAT !!

I saw the correct mark on the crank pulley at 3:52 minutes from beginning of the recording, it was the collected dust and oil which mislead you. I do not blame you as it happened to me as well. You are doing great, well done. It is a pleasure to watch your videos. Thank you very much
Good eyes kid
You sir are top of the line. A1 THANKS FOR THE FINIAL RESULTS ON THE O2
Great video! Thanks for the extra mile as normal. I like doing an old job now and then, it's funny how stuff comes back!
Thank you for the video you really went the extra mile.This brings back a lot of memories
Paul, Great vid. I've seen you lay in that same parking lot time after time. I have a dirt drive way in front of my garage so I feel for ya! Little tip if you ever see a old weight lifting bench on the side of the road, grab it. The cushions on them are great for laying on the ground and are very portable because of there compact size. Perfect for Pete's parking lot and will make a perfect addition to your mobile tool chest!
You deserve your own shop,'well done!
Great video as always. Glad you enjoyed rolling around in the ice and gravel
thank thank you for all the testing because this just found out the problem why my truck has been acting like it has for the last 7 months it has been acting the same way hesitant surging low power I've changed so many parts and still had the same result
How does it feel to be Scanner Danner? Click here → 51:44 to find out!
+briansmobile1 Kinda bad A right?
+briansmobile1 thanks Brian for the plug!
It feels RRRRRRRReally Good. LMAO
lol, I think I missed this last time. super funny, thanks again brother
Awesome stuff again, Paul!
I love this video working on old school technology nice fix thumbs up
You are a genius!! Learned so much from you!! And I'm currently in a BMW step class! So need all the knowledge I can get! Lol
how can anyone dislike any of your videos? they are all informative. Thanks again
because a lot of people just want solver bullet fixes, not long how-to videos
That was great I did the same truck a few weeks ago and my verus was doing the same thing going back and fourth not sure why. Thats a great tip on testing O2 wiring
hey man just wanted to let you know how great your videos are thanks
Thank you for filming all of this. Folks don’t get the conserntraion it takes to repair older cars and trucks.
Apreciate all u do...for real=).. think the hardest thing to do was getting underneath the truck when its cold and wet...thanx for all ur hard work.....
timing light! That brings me back!!! Done one on a rebuild of a ford 302 two weeks ago..... 1973 Comet....
Excellent video, I really appreciate you posting it.
SD has done it again...Great video...
I really appreciated what you did, you are a super teacher :)
Great throwback video. Got worried there in the middle of the video that the exhaust leak you mentioned early on was causing a faulty O2 reading. Nice diagnosis.
nice video paul, also a positive way to take care of the comebacks,good attitude , nice my friend
Another great video, thank Mr. Danner. Hopefully it stay's away this time but, I am sure part 3 would be great too. Thank you again
Thanks Paul. Learned a lot as always!
Good tip on "cause or effect", it's tricky to distinguish between the two sometimes. EECIV is one of my least favorite systems to diagnose. On the previous video, I would suspect a bad splice, but with no good info on older systems it can be tough. Good fixes!
This was the best video ever made...Why? It shows you're human!
Your a great teacher looking forward to joining your class
Looking forward to having you "in class" :-) Thank you!
Your the coolest. And I appreciate you laying on the ground for us
Thanks brother
quality from scanner great video
That 300 inline 6 engine!!! Tough as nails i refuse to drive anything else. Best engine ford ever made
I had 1 and it was garbage.
Excellent video well explained. Thanks for the time taken .
Awesome troubleshooting session really enjoyed this video.
I find it amazing the different things that can cause performance issues like this. I have a 2004 Honda Odyssey that was giving all kinds of codes from O2 to rich on bank 1 to lean on bank 1 to Evap system . . . . . Long story short, the little rubber grommet on top of the fuel pump (inside the sending unit assembly) had cracked and was flaking off. After a ridiculously long search, I was finally able to obtain one and replaced the broken one. Now, the thing runs almost like new. Before that, it would run great with a full tank of gas, but once it dropped below 1/2 tank, it would hesitate and balk, sometimes nearly die out completely!
Great video
Thanks for all sacrifice you made
As soon as you mentioned your book I ran to look at it and now it makes more sense when it's applied in real life.
Which part Juan? The O2 signal circuit test?
Section 10 signal circuit integrity test
Ah the opposite code test! No doubt, great example of when to use it huh?
I appreciate all you teach😎✌
As always thanks for all you do!
Reminds me of a problem child we had that I posted on iATN in 2013. Same type of scenario and outcome sort of...
1999 Jeep Wrangler Sahara 4.0L Hesitation, Surge, Cuts out, Stall, Misfire, Intermittent Sensed
The scanners reported a weird #4 misfiring --- so we went down that rabbit hole big time - shame on us. Probably we were psychologically motivated to pursue that angle because we we scared the rebuilt engine that we at the time we recently installed was awry and that would be blood on our heads.
Here is bottom line summary as I closed it in iATN "Well here we hope is end of story. After persistence on part of tech collecting scan data it was apparent that on occasion O2 sensor output was weird. We electrically tested circuit and settled on the sensor itself.
New OEM sensor installed (consulted with dealer master tech first) and vehicle running perfectly. Now O2 output not just fuzzy perfect but always spot on perfect.
Finding this eluded us because O2 output seemed OK enough (and was 90% of time) - but that "hidden" 10% was kicking our tails.
Also sometimes it pays to just ignore a mystery and go for the obvious. We believed the tombstone miscount graph (still there! consistently! still mystery to all including dealer master tech consultant) was clue to problem. When the common O2 sensor drop out seems to have been the cause of driveability problem. "
I would have diagnosed a faulty stinky tree hanging on the coat rack inside the cab. lol Great job getting the antique to run well. Paul your videos rock!
Excellent, I'm still back tracking, I had these symptoms initially, changed the O2 and still had same symptoms, so I changed the a bad hose on the fuel pump but in addition my truck stops running intermittently, no check engine light on key position, no start, crank. 00Mazda B2500SE 2.5L I have no diagnostic tools except a volt meter & test light. Thank you for sharing your knowledge & experience.
find out what you are missing when it doesn't start. these videos may help

With the car key in On Position found the Relay that Controlled the Check Engine Light and Changed that Relay (Auxilary Power PCM?). Now my truck starts Dan. Approximately what is the most I should I pay to get a Full Diagnostic Scan at the Dealer where I originally bought the truck? Don't have any codes and have to put the truck back together before I can road tested it. But I did leave the engine running for over an hour and it didn't die.
This guy is great! Good mechanic
i have this exact same timing light and its gotta be over 15 years old now still works like a charm, also remember the fan blades are invisible when spinning watch your finger tips it doesn't feel good usually wont cut ya
I think this is one of the better in the field video's you have ever done. You didn't seem as stressed as I have seen you before. I have worked on many trucks like that and I was screaming for you to check the O2 sensor. LoL. I don't think you heard me though. They only try to correct for so long before they go into open loop. I have also seen EVR solenoids stuck open allowing uncontrolled vacuum to the EGR.
I'm kinda glad they don't build them like that anymore but at the same time I miss the simplicity.
Very informative. Many thanks for you sharing your knowledge.
Man, that was cool...would love to have one of them Snap-On scanners, you did a great job on the old Ford...luvin' your video's man !
Fantastic video. Thanks for your work.
I actually wish I was able to go to the states and be taught by you. If you ever come to Ireland, please let us know on your website. I want to shake your hand and thank you for all the things I have learned from you.
Thanks so much!
Great video! Brings back memories from my 85 Cutlass Supreme I had in high school...trying to set the timing. lol.
JoeyPete my first car. Same year.
I'm learning more from your cockup videos than I ever learned from anyone else's regular how-tos.
Probably because this is my style. lol
I appreciate it. It was not easy getting under neigh the track at all, specially on wet and frozen gravel.
Learned a lot from this, thanks!
Hey Paul long time no comment….
Love coming back to watch your older videos, especially if they are about the old fords pre OBD ….
I’ve got a super rich running engine I’m dealing with on my 86 e-150 302 going to check the MAP sensor and scan for codes tomorrow!
This motherloving truck keeps biting me 🥶
It’s a habitual line stepper 😅
Awesome Paul, love the video.
Man I'd love to go on some diags with you sometime been working on cars for 5yrs in the field. Mobile repair is the best to learn on live problems with no codes. I have the u scope and a 2 channel. I appreciate the time and effort you put into your videos. I met Eric at SEMA. It's easy for people to talk trash online. I'd like to see you speak at SEMA. Or come out to my shop when I build one. I have cardboard.
Been a Mechanic for 30 years. I always Cut my hood Strings. Got mine grabbed 29 years ago.lol Love Cardboard used it for years. In Cold Wisconsin, It works great in the winters.
I just got an 88 F150 with the 6 cyl that is exhibiting the same faults as this truck... stumbles at part throttle with the EGR hooked up, unplug EGR and it runs great. The valve itself moves fine, vacuum control is fine, and the position sensor measures OK. I hadn't thought to check the O2 sensor - now I know where to look next!
Greatgreat video...really appreciate your effort,paul
Good Job!! On to the next sunny beach!!
Thanks for showing the waveform of the O2 sensor. Now i am sure that my O2 sensor it's fine.
I was just going over some of your past videos as I am getting ready for the ASE L1 exam, and after watching this video I have to say that maybe some Manual Transmission Driving Lessons are in favor for you sir. haha. Hope you get a good laugh as I did. Great video.
Thank You for the in depth video. I have an project ford pickup with similar problem. Including the door that doesn't shut correctly : ) Nice to see someone working on older units.
Big Thanks+Respect for you and what you do ,
Thanks buddy, had this same issue with my 89 4.9 Econoline
Great video man!
Great video. Rode with you all the way thru. Who cares about the seat belt. With trying to figure out what was going on, I'd too would have forgotten to buckle up. Good troubleshooting. Thumbs up!
+Keven G thanks man
-super video scannerdanner has allway
Hi Dan, great video, man thanks for doing the, 'o2', testing on the after-fix, considering the working conditions, very Koool 👍 👏, sure appreciate, "i feel your PAIN"!!, GREAT DIOGNOSES, You must know your FORDS!, KEEP 'UM COMING, (Ur-Vlogs), Take care, & see-ya!!....
Love watching your EEC-IV videos! Loved it more if I lived closer to you so I could pay you or your services 😀
thank you for your time and knowledge
Thank you for watching!
