In this video Ivan ( a SMA Viewer from PA ) and I start a diagnosis on a 2006 Hyundai Tucson that was giving me fits with a P0173 Fuel Trim Malfunction (Bank 2) . First let me say I am thankful for the new friendship and Ivan's willingness to stop me from throwing in the towel and being an inspiration to move on despite how busy the shop was and bring his vast knowledge to the table and share selflessly. Thank You again Ivan!

    Maybe if you remove the dead squirrel from around the MAF sensor it might start working properly…

    hello I am a retired Toyota master tech I had a Toyota v6 3 .0l or 3.3l that had this issue and it drove me nuts it ended up being the pin in the end of the cam that the cam gear for the t belt attaches to, was damaged and caused the cam to be out of time just slightly you could not see the damage till you took the cam bolt out that holds the gear on, that the pin was just slightly out of square with the cam .I don't know what the set up is that holds the cam gear to the cam but I would be checking that on that bank.

    great video, great guest!
    what would a link to Ivan’s channel or the name of it be?

    This is one of them problems it could get you and also drive you nuts I would of Figured it has a medium to large vacuum leak Eric O @SouthMainAutoRepairLLC

    The other shops history is interesting how much they have done and never changed the issue This video series is a good one @SouthMainAutoRepairLLC

    This case study is one of my favorites Eric O, especially Part 2 @SouthMainAutoRepairLLC

    How about alot less useless chatter and get to the point already.

    Without the mass airflow sensor plugged in and things are being run by the oxygen sensors with that tell you that whatever the oxygen sensors report to is faulty? I am just a plumber guys❤️🇺🇸❤️🇺🇸❤️🇺🇸❤️🇺🇸❤️🇺🇸❤️🇺🇸🇺🇸🇺🇸

    Two brainy car guys.

    Check that sensor one is not pop out of pipe that happen to me

    PCV valve? I had a Ford Focus. Put 2 O2 sensors. Took me months to figure it out. A Ford mechanic told me in a forum to try replacing the PCV valve and it fixed it. It was p0171 code engine lean bank 1.

    Watching this again for the first time. Great refresher!

  15. Avataaar/Circle Created with python_avatars crusinscamp says:

    From the auction, we know what that means… Mine had a broken wire deep in the wiring harness. Twelve pages of printed wiring diagrams later, evidence of someone picking at, and failing to fix the problem… We got her figured out, which was satisfying.

    Two of the best in the business working on this car. My truck is jealous!

  17. Avataaar/Circle Created with python_avatars B. P. says:

    Maybe high resistance in the wiring to the 02 sensor power or ground

  18. Avataaar/Circle Created with python_avatars Mike Mardis says:

    I’ve watched just about everyone of your videos and just came across this one. I never thought I’d see you in a pristine Lexus hat. Good move on the hat swap.

    Lolll🤣🤣 stupid kid man always trying to said somting shutup we dont give a fuck about u 🤣

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

    That would drive me mental. Must be frustrating as hell. Just the fact that the previous guy has a long list of things they have eliminated. Not saying they didn't do a perfect job in each case or anything, but it's the question in the back of your mind…did they run the bead of silly-cone all the way around the intake duct, and every other uncertainty. Unless you have seen it with your own two eyes, it may or may not have happened.

  21. Avataaar/Circle Created with python_avatars Simon Jones says:

    the lean run on bank 2 can only be caused by a fault on bank 2 you found a small vacuum leak and proved it with brake clean I think you have found the problem small vaccum leanks on v enginesare allways going to be a pain but you were able to pin this to bank 2 diagnosed as far as I can see

  22. Avataaar/Circle Created with python_avatars Russell Booth says:

    When I was doing a small automotive tech course in 1994 they had that trouble with a late 1980's model Daihatsu Charade,they had a exhaust gas analyser hooked up to the tailpipe which was reporting a lean air to fuel mixture,they suspected that the car may have had an exhaust leak.

    If the Hyundai has a twin exhaust system,maybe you can hook one of them up to the affected cylinder banks tailpipe to confirm that the air to fuel mixture is actually lean.

    If it's not leaky valves, incorrect valve timing,a faulty O2 sensor, faulty wiring or a blown cylinder head gasket then I would look for an exhaust leak,it could be caused by a sooted up O2 sensor which is underreporting as well !

    Leaking injector bank 1

  24. Avataaar/Circle Created with python_avatars deno spyridon says:

    O. M. G. Love it.

  25. Avataaar/Circle Created with python_avatars Kemp Wyatt says:

    Bank two timing is off

  26. Avataaar/Circle Created with python_avatars Attila Kohbor says:

    It is definitely an air leak at bank 2 only , it could be a crack at the exhaust header .

  27. Avataaar/Circle Created with python_avatars Michael Serrano says:

    Who's the guest here? Looks like Ivan took Eric's Business 3

  28. Avataaar/Circle Created with python_avatars Roberta Williamson says:

    Had a similar problem with a 1985 Buick Le Sabre ,it turned out to be an exhaust manifold leak at the cylinder head connection,it was tiny,but screwed up the o2 sensor readings,because between exhaust pulses it would suck air through leak,interesting to say the least,car manufacturers had started to use computers to design exhaust systems to scavenge exhaust to increase performance and drive-ability ,but the exhaust had to be free of leaks so the sensors would produce correct readings,a stupid cracked gasket.

  29. Avataaar/Circle Created with python_avatars MrJoey Man says:

    Ivan is great, but he should let you talk without interruption. It gets chaotic trying to listen to both of you. Im going to sub to Ivan's channel also.

  30. Avataaar/Circle Created with python_avatars JoeJ94611 says:

    I think getting viewers’ suggestions is a great idea.

  31. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    Oh boy! THAT'S A STUMPER FOR SURE! Great Video!

  32. Avataaar/Circle Created with python_avatars Rick Williams says:

    Eric mentioned Ivan's YT channel on one of his videos and I've been watching both channels for the last few weeks. Both have great content and it's so cool to see you two work together!!!

  33. Avataaar/Circle Created with python_avatars Corbett Knowles says:

    I was thinking air engine intake sensor but not sure if Hyundai use those I'm not Hyundai person

  34. Avataaar/Circle Created with python_avatars Canadian Tanker Yanker says:

    Obviously the thingy isnt thingin

  35. Avataaar/Circle Created with python_avatars Duncan Mac says:

    Can't you just click on the "Fix it" icon on the scan tool? That should do it right? Thanks for the video. (I'm kidding of course)

  36. Avataaar/Circle Created with python_avatars Khalil Rehman says:

    Hi. I have sane car 2006 Hyundai tucson now it's showing intake air temperaturesensor 1 circuit high input PO113 and I really coulnd find it, I'm from United Emirates kindly please help me.

  37. Avataaar/Circle Created with python_avatars Bob Pegram says:

    Gee Eric O. you are a real You Tube mentor! Ivan does a good job on his Pine Hollow Diagnostics channel now. I didn't know this was from before he set it up until the end. I hope you guys still get together and mountain bike or some other fun.

  38. Avataaar/Circle Created with python_avatars Bob Pegram says:

    I just found this three+ year old pair of videos! Amazing thought trip to the answer.
    One thing I can say is: the guy who invents an "aluminum magnet" will make a fortune!
    I DON'T repair cars for a living. You should be thankful that I don't! I was thinking, "Ok, so replace the faulty cam and it'll purr." Sure, it would purr for a few weeks or so with the more correct idea of a head replacement, but then watch out! I would love to have seen the oil filter from before the oil change.

  39. Avataaar/Circle Created with python_avatars Lui Bove says:

    I have an 07 V6 Limited, & the vehicle stutters at a stop while in drive. This only happens after you run the car, then shut it off, leave it for a bit, then drive it again. Already changed plugs & wires, cleaned air intake & siliconed, cleaned air filter, ran the vehicle to clean the fuel system a few times. This issue doesn't always happen, but is worrisom as it may start stalling. I hope this was enough but doubt it.
    BTW Excellent Vids!!! Keep up the good work!

  40. Avataaar/Circle Created with python_avatars Jon Russo says:

    Did u check that manafold for cracks and any other cracks in seen or maybe the silicone made it go lean also????

  41. Avataaar/Circle Created with python_avatars Joginder Deol says:

    Audi Q7 episode plz

  42. Avataaar/Circle Created with python_avatars David James says:

    look!! it's the dude from the cover of Mad Magazine!!

  43. Avataaar/Circle Created with python_avatars Northern Ireland Fishing Reports says:

    Not sure if il get a response but I have one these Tucson ( unfortunately) long story short. Noticed the back wheels locking up when going backwards. Looked under and seen the rear differential had oil pissing out. Changed the diff with a new one. But still having problems. Now when in normal 2 wheel drive there is a slight buzzing noise and when reversing in 4 wheel it locks up the back wheels. Like a binding or being held back. Any ideas what this could be. I've read up on the AWD and 4WD. Is it correct to say that the wheels will lock up if on a normal road and the buzzing sound may be the front differential needs changed too. Any advise from anyone would be good.

    Brakebooster pipe valve or brakebooster leaky?

  45. Avataaar/Circle Created with python_avatars Scott Rabideau says:

    I am having similar issues
