540k MILES?! Toyota Sienna: Intermittent Misfire

[@Alex-io5el]

I'm nowhere near this mileage, but my Sienna just crossed 315k. My family got it when I was only a year old and I'm currently the second owner at 23 years. Everything from preschool THROUGH college and even to my first date has been with this very car. It's been such an amazing vehicle and rides really nice. Unless you're really trying to do so, the 1MZ-FE is unstoppable.

[@Ram14250]

Ivan, these type of video's featuring high mileage vehicles that are in decent shape are amazing! Really enjoyed watching you work on this one. It seems Toyota and Honda seem to have replacement parts for their older cars unlike the domestics. GM is famous for "No longer making that part for a 2018 Malibu". Here's to another 500K miles on this Sienna!

[@RickyRisnandar]

one of many reason i still keep my 93 corolla

[@kevinbarry71]

Yes, a huge difference in philosophy between Toyota and Honda and companies like GM. GM is all about now. No tomorrow. Frankly I don't understand how they can sell any vehicles

[@adamtrombino106]

I was just at a local Dodge dealer to get a heater hose for a 13 Dart w the 2.0. It's a formed part with rather tight bends so I didn't want to chance just making 1 and it looking like a hack job. It was listed, but no one had it, and na aftermarket. The guy finally found 1 in NJ! Shipping cost almost as much as the part, and it took 5 days to get. While at the counter, I overheard a tech talking with another counterman. Was looking for some sort of module for a 16 Ram PU. Part was discontinued! The dealer's policy is not to install used parts...

[@teekay_1]

@@adamtrombino106 Did you ask them what they tell customers? "Hey buddy, Dodge doesn't make parts for your 5 year old car. I suggest junking it."

I thought my former neighbor's Previa did good, he put a used engine in it at 395,000 miles. I lost track of him shortly after that, his wife asked him to find a new place of residence. I bet that Previa is still going strong!

[@douglasmontgomery6315]

Ivan, Since you already had the scan tool connected at the beginning, I would have looked at Fuel Trims. Ignition misfire have less corrections than fuel caused misfires. That would have given you even more direction and in this case, saved you from pulling out the diagram and scoping injectors. Thanks for sharing.

[@calholli]

Always efficiencies to be made.

[@HeyBirt]

Years ago I was surprised to find that the spark plug wire sets from Toyota come with all the wire separators, slips etc. For my old Toyota truck the cost difference between aftermarket and Toyota was about $20 but it would have been worth it for all the little 'extras' Toyota included.

[@juanrodriguez-ry6yt]

the factory wires last just about forever unlike tht blue ngk or the denso wires i have tried them all i been working on toyotas since the 70s

[@gtemnykh]

Had the same exact experience with my 96 4runner, replaced a newer set of $40 NGK plug wires that would misfire in the wet. Installed the $60 OEM Toyota set with the separators etc as you note, perfect.

I was driving an old Toyota in outback Australia when the brushes wore out on the alternator. After a quick check of the fan belt, I drove for another 3 hours to the next town with everything off (AC off) . A local garage put new brushes into the alternator and away we went... That's how motoring should be...

[@ScottDLR]

When it missed more under load, I figured that was an ign issue. Anyone ever seen an injector act like that? (serious question)

[@PineHollowAutoDiagnostics]

good point :)

I was thinking the same thing. Thought I'd look through comments thinking someone else must have already made this comment. Here it is. Thanks for all the great vids Ivan!

[@conrailfan6277]

Sweet, it just goes to show that proper maintenance pays off in the long run Ivan!!! Over 20 years and 500k proves it, plus don't skimp on plugs, wires, oil or any other replacement parts, if your not modding anything than OEM is the go to for repairs, Chinesium crap will bite you in the backside!!!

Toyota is truly an amazing auto maker. 540 000 miles is more than 800 000 kms. That is insane.

[@mistermatsuda]

I would've loved to have purchased OEM plug wires from the dealer for my '00 4Runner but they wanted $120 or so. I ended up settling for NGK's that were $35 and they have worked great for 4 years and counting.

[@timlawrence3264]

I have a 07 Camry with 188000and the only thing it’s had is two alternators and a serpentine belt plus regular oil changes. It has the engine with oil consumption issues. Changing the pcv valve helped a little. I need to put a valve cover gasket set on it. Valve cover doesn’t leak externally but it has minor leaks on a couple of the round gaskets for the spark plug hole. I think that would cut oil consumption a slight bit more. Thanks for the Toyota vids.

[@arthurfricchione8119]

That’s correct Ivan. Take care of the old ones and they will be around when the new electronic beasts are gone. 👍

[@johnhiram1207]

Yup some of those older Ford pickups last crazy miles like Toyota’s !

There good trucks. I have a 2001 Tundra with 257k I picked up for 1k for my son. We replaced the timing belt and fixed about 10 other things as it never had much maintenance, maybe oil changes. Now it’s mine as I bought it from my son and it runs like a new truck.

[@Terramoto73]

These engines, and ignition systems are quite picky. Be careful with plugs selection, wires, and routing. Had a bad missfire on a 99 4Runner. turned out to be a bad wire, and the routing needed to be correct.

[@williegillie5712]

It’s amazing, back then they actually built cars that lasted. Now days they sit parked at the dealerships and no one offers a bumper to bumper 100,000 mile warranty any more. You pay expensive shop repairs with less then 50,000 miles on the odometer. Things have sure changed, but not for the better.

[@Garth2011]

BIG success on this one. Real ignition wires get put back on the engine ! Going from those awesome Toyota perfect fit wires to Autolite basic generic fit wires is a great improvement for looks and well as long term reliable function. Time for an engine bay cleaning and a new or welded exhaust manifold and that van will sound so much better. With those miles on it, it surely deserves a little more investment.

[@davidgrandstaff5047]

Hey Ivan, quick question about your scope setup. Did you have an attenuator on channel one or were you not concerned about the voltage spike on the control wire(zener diode, circuit layout, ignition setup, etc)?

[@NextLevelAutoDiagnostics]

His scope doesn't require an attenuator since it can handle inductive kicks from injectors.

[@riblets1968]

I heard some good things about the 1MZ. If this is a typical example, it's probably one of the best automotive engines out there, along with the 5VZ-FE perhaps.

[@spelunkerd]

I noticed something peculiar about the injector waveforms. If you scrub the video (with < or >) slowly around 6:43, the sloped current ramp happens mostly before the injector is grounded. There seems to be a double activation happening, and when you look closely on the voltage trace you can see a small blip in the voltage when current starts. I was going to put that off to a difference in the design of the injectors, or maybe extraneous artefact. But then when the car stops misfiring at 7:00, the current ramp timing is more in line with what I was expecting to find. Why? Was the current probe picking up extraneous current from another branch fed by that same fuse? Why did the timing of current ramps and voltage change when the misfire went away? Is it related simply to higher rpm?

[@rightlanehog3151]

Only 540,000 miles and the problems are starting already?? So much for that over-hyped Toyota quality.

[@hooptierescue2540]

Rather than only swapping one part at a time, what I do to make the process a little quicker is move all the parts in the suspect cyl to different cyls, like if 5 is suspect, the plug may swap with 6, the coil into 1, and the wire to say 4. Then in one test firing I can usually tell EXACTLY which is bad.

[@christophervanzetta]

Same here. Eliminates so many variables in a few steps XD
