Haunted Hyundai...is BACK?! -Part 1 (Hard Start-Misfire-SMOKE Diagnosis) 

Ditto. 35 years in the shop here. Ivan, Eric and Dan. These 3 guys have excellent skills and they are thorough in their diagnostics and explanations. I recommended all 3 channels for my son who is taking over when I retire. ;)

@@Ismail-1983 Yeah, what he said. Eric O over at SMA. Scanner Danner is who I meant by Dan. I was still only halfway into that first cup and wasnt up to all that typing yet. LOL!!

@@farmermiyagi1338 I figured Dan was DiagnoseDan. He's good too.

You didn't talk your son into a different career? lol

@@billmonroe8826 Absolutely not. All of my boys are in the trades. 2 in auto repair and one in HVAC. This is not a glorious job but if a man is good at it he can make a fine living. ;) Not to mention they will be a lot handier to have around than say a Geology major.

They are good enough - general rule of thumb is to change them every 7 years.

where i worked my boss said it's the customers car if they want to check on how it's being repaired, they can as we are doing the job correct, we have nothing to hide

Absolutely! Ivan comes from the other side of understand electrical items, and knowing mechanical things. After all, when one is from Russia, they do "Russian repairs" if required! LoL 😂

And they have had to add back in secondary port injectors to stop the carbon build up issues on the valves. Beggars belief.

I honestly belive petrol and direct injectors dont mix well(since the fuel bearly has any lubricating propretis and the injectors are tight tolerances)

These are great for supercars.

OE’s love the control that it gives them in the chamber though. It’s unlikely port injection will ever make a come back despite many drawbacks from a cost of ownership point of view.

I'd be curious to know if its just cheap poor quality parts that are the problem (like is the norm for the automotive industry these days) or the ethanol content of the fuel or if it is just the technology itself which isn't viable. I know on the Toyota's they mix port and direct injectors partly for performance reasons and also probably to stop carbon build up in the intake. At the rate they seem to fail I really can't believe that it produces any savings or emissions savings overall because the parts have a relatively short life.

Interesting you say no lubricant. Not saying you're wrong. Just saw many posts about that he should have used lube.

@@dans_Learning_Curve Nope. The factory doesn't use it. It's not an o-ring. Lubricating it will actually compromise the seal. Think of it as press on seal. Like a wheel bearing. There may be some out there. Idk every manufacturers procedure. But all the ones I've done GM, BMW, Mercedes, VW, Kia and Hyundai no lubricant.

@@edwinlomonaco6754 ok. It'll be some time before I owe a direct injection gas engine. Check out my 1958 carbureted Plymouth Suburban. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9jJxV_qSNmg.html

Especially considering its a Hyundai - they are nice enough vehicles and are cheap for what you get but they are designed to last for about 7 years/100,000 miles and then they drop to pieces. In the UK that is their warranty period and from what I have seen it gets a bit of use.

This Hyundai made so much smoke that it negated all the CLEAN AIR TECHNOLOGY 🤣🤣🤣

Should replace them all, imo. All of them are just as old and unreliable. With the labor involved to replace one, you'd be very angry if 6 months later that labor had to be done all over again for another injector.

@@bills6093 I wouldn't be very angry, at best I would be annoyed at myself. There are many other things in life one could consider one would be "very angry" at, the decision not to replace all injectors at the same time is not one of those situations.

@@robpeabo509 It's your money to waste.

@@bills6093 You seem nasty Bill S. It seems you do not like differing opinions to yours. I have no more to say after this to you.

Was it using oil? EDIT Do you check your oil or do you rely on it being okay until the next oil change?

Shouldn't that be a warranty engine replacement?

Yes I checked my oil regularly and most of the time would service it myself. I became concerned when I saw what I believed to be excessive oil usage. I was concerned enough that I took to the dealership and they performed an oil consumption test. Of course they claimed that what I was seeing was "normal". This is probably why I got no push back whatsoever when I filed my warranty claim. They did ask for any documentation for maintenance records. I guess I have to give them credit for honoring their powertrain warranty but then again they should. Within 2 weeks of getting the vehicle back with the remanufactured engine I unloaded the Kia (no) Soul.

@@chrissimmons9969 okay 👍

Yes installed but not sized

@Jonathan A Yes, and many of them have conventional fuel injection as well as gasoline direct-injection because of problems with carbon build-up due to no fuel passing over the intake valves. These older Hyundais have only gasoline direct-injection. LOL.

Loses value,I bought 2020 palasade for 48;000 and sold to carvana for 57,000,I win!

But the government serves us and our best interest... 😂😂😂😂😂

@Jay, isn't DI more efficient under load? Ivan did mention 28mpg; show me another 3.0 V6 SUV getting that mileage? Kia/Hyundai vehicle owners, with that now infamous 2.4 I4, thought they'd be left holding the bag, too; 'till they got smart: got together, organized, and filed that law suit - Kia/Hyundai had to step-up. Diesels use DI, and they don't suffer that Hyundai's injector failure. Why didn't Hyundai use a known, trouble-free DI injector design? Money - the bottom line, that's why! Are their other vehicle manufacturers using petrol DI, and not in experiencing such DI failures? Of course they are! It's Hyundai's fault, not DI technology; nor certainly not the Govt's. What I'd love to see is Ivan cut open that faulty injector and do a post mortem. Did the spring break, or just weaken? Is there data out there on DI injector spring specifications (length, compression strength, etc). Something kept that pintle open: weak/broken spring, computer, maybe? I'm still waiting for him to disect that Lexus transmission... Plenty of those still in service.

2022?? Wtf lol

@@PineHollowAutoDiagnostics only 2k miles too, hasn't even had an oil change yet, may end up with a new engine depending on what i find inside.

I think 90s cars are a good compromise... Bulletproof simple port fuel injection 👍

Yes, that is the correct decision. He'll be very angry if that labor has to be done all over again in a few months. All the injectors are the same age and type, so it wouldn't surprise anyone if another one failed in a couple months.

Why not all 6?

@@PineHollowAutoDiagnostics Yes. all 6 would be best, but those three at a minimum. Perhaps there is a problem with heat or something on the rear bank? Plus you did have a reported #3 misfire, which might have been that injector getting ready to quit. But, it's not our car.

@@PineHollowAutoDiagnostics Agree if the front 3 are buried just the same !

Moving moving pintle through a magnetic field will create an additional voltage "back EMF" that you can see as a "pintle hump" on the oscilloscope. Review your physics notes 😉

Same car?

@@PineHollowAutoDiagnostics no sir it's a Cadillac XTS. I've been struggling with this issue for months and I just can't find a good shop that will actually troubleshoot it. It's to the point where I bought a cheap autel scanner just to log the misfires and then discovered it's losing a lot of fuel pressure over night. Cyl 5 will have some gas in it in the morning. Apparently it's a big pain in the butt to get the injectors out of this thing though so if I do one it's going to be all 6.

🤣

Better Emissions and horsepower would be a short answer butt I guess the question is rhetorical.

Improved fuel consumption AFAIK. New buyers compare numbers without considering maintenance headaches.

combine that with the toxic mix of EGR exhaust fumes mixing with PCV crankcase oily fumes, forming a carbon sludge gradually blocking intake system.....seems all postive here :)

I think DI offers a better more complete coverage in the combustion area than standard port injection. There is a more complete firing of the fuel.

Much better fuel economy, performance and emissions. Carbon buildup can be an issue, though less so if well maintained and using synthetic oil. Injector failures like this don't seem very common.

Now it gets 10 LESS mpg with a broken gushing injector 🤣

Better not work on any modern diesels then, they get up to around 30,000 PSI and if you think parts are expensive for GDI better not look up parts prices for diesels.......

@@lustfulvengance Diesel fuel is NOT GAS!! Gas at those pressures is close to ignition!! Let alone a fuel leak.. Spray high pressure gas all over the engine compartment.. Do you understand what a Octane rating is?? Reg Gas 87... Diesel 20-30!! ( the conversion of a diesel's cetane number ((40-55)) to Octane is approximate) Having high pressure flammable fuel flying around under the hood is a recipe for disaster.

Put an ignition source near highly atomized diesel fuel at 30000 psi and tell me how not flammable it is! The risk of liquid injection injuries greatly increases with an increase in pressure as well. My statement holds true, this guy is afraid of GDI, he better not get near a modern common rail diesel 🤣🤣🤣

​@@lustfulvengance GAS is 100 times more dangerous than Diesel AT ANY PRESSURE and even at 30,000 psi DIESEL is less flammable then GAS.. Get a degree before you spew..

@@jwray9799 Dangerous is a relative term, water is dangerous in certain instances! Diesel fuel may be slightly harder to ignite but it also contains a lot more energy, it will burn a lot hotter once it is ignited and believe me highly pressurized atomized diesel fuel is anything but difficult to ignite! Nobody's debating whether or not highly pressurized fuel is dangerous, I was simply stating that modern common rail diesels present more of a risk and are also significantly more expensive to repair. I'm not entirely sure what you're trying to achieve with your argument here 🤔🤔🤔

That's an option for sure. Was easier to hook up this way than trying to stuff amp clamps at that tight connector 👍

Absolutely agree. And then some 😅

I think Ivan has said before that the system occasionally reports the wrong cylinder misfiring. But I see where you are going, I think. Is #3 injector getting ready to fail?

Are you talking about cleaning it was n place or removing it to clean it?

@@dans_Learning_Curve I meant when it is in the engine with a cleaning agent.

Absolutely not...it's FUBAR

This direct injectors are like those in diesel truck very high pressure and they are normally just replace.
