I used lots of this video to get to a #4 cylinder fault code for a misfire. Wires were too short from factory in the loom and at 70,000 km they both broke from the fatigue of being too short of the #4 injector plug. Mine is a 2019 4Runner , great video and good detail. Appreciate you taking the time to film it, I'll do the plugs while I'm in there.
I am in the middle of the job right now. I think you did a great job except for one small problem. On the back of the plenum where the heater hoses and injector wire harness attach, the connections HAD to be broken to get the plenum loose. I know you made a short comment about this in the video, but you need to stress there is NO OTHER WAY to release these connections that I could come up with. Thanks anyway for posting this - it really helped me a bunch!
I have to correct this assumption. You DO NOT have to break these connections. The upper most has it's release tab on top, I use a 90 degree hook tool to pull up on tab and a screw driver to push the connection off. Lower one is a little more difficult because the release tab is on the bottom, use same 90 degree hook tool, estimating where the tab is, lift tab (downwards) and pull right off. These can be difficult if it's your first rodeo but these in fact can be taken off without breaking, took me like 2 minutes for both.
Thank you for this video! I’ll be putting it to use tomorrow to replace the injectors on my son’s 2005 TRD Sport to hopefully fix a P0420 that new cats and O2 sensors didn’t fix…
Man…after watching this I honestly think I will just live with my 14.5 mpg MT 4x4😂…at least now I know where the darn injectors are hiding now🤣. Kudos for doing this
I have a 2003 Prado with the 4.0 GRFE with 200,000 miles but am getting 9.5 miles per gallon! With no fault codes. It runs sweet but guzzles petrol- looking at replacing O2 sensors and cleaning/ replacing the injectors
Thanks for this video! I need to pull my intake so I can deal with a knock sensor. I couldn’t find too much info on taking the intake off, and I definitely didn’t expect to find someone telling me each and every socket size! Thanks again!
Thanks for sharing. Very nice vid. 6/5 but I took half a point for not wearing a mask and half a point for not washing your hands before touching the injector seals so you get 5/5
Excellent video, one of best I've seen! Thank you. The injector holes in the head were very dirty. It would helped to know in advance how to prep the area because it was difficult to clean out...
So I actually had a retainer fall into the injector port! What are the odds? Luckily I had a Boroscope camera and able to retrieve the clip by putting a dab of grease on tip and stuck it to retainer and pull out like the game of “Operation”!
@Jabo The Mechanic So what was the final outcome? Did the gas mileage improve for the customer? Did you test/send out the old injectors and if so, what was found? (meaning, was this even necessary?)
what made you lean towards replacing these? Did you have a misfire? what P code? fuel consumption excessive? and what injectors did you run with, OEM from toyota or OE spec from other manu?
Misfire #3 cylinder changed the coil and plug still have the same problem, so I'm thinking fuel injector. At 67 I'm not sure if i want to do this again. I replaced a knock sensor many years ago. It pretty much was the same process. I'll study your video to refresh my memory.
It was the #3 injector wire which came lose from the female connector on the wire harness. It broke when I was did my knock sensor and so I mickey moused by stripping the wire insulation and plugging it in the female connector and electric tape the shit out of it. Lasted 8yrs. What a relief!
05 4runner V6 4.0 So apparently this Tacoma has my same engine. I am hear because I have P0011. I changed the VVT solenoid on the drivers side, but on the passenger side, that U shaped hose is in my way. Oh, forgot to mention that both VVT solenoids fell apart in my hand. I got the drivers side out by using a Tapper to thread a bolt, and a slide hammer 😞 Same issue on passenger side, I need to thread a bolt with a tapper, but that hose is in my way, and is the intake plenum. I might be able to get in there with the hose out of my way, but there are no clamps and seems just fitted on the fuel rail ? Is there any trick or concern with removing that U hose, and put it back ? Even If I remove the hose, I think I will half to remove the intake plenum to have the space to get a tap in there, and slide hammer to get the broken VVT solenoid out... But if I do end up going that far, I appreciate this video, as if I end up going that far; Might as well replace the injectors while I'm there 🙂
I noticed there was a bit of oil residue in the valley of the engine beneath the injectors. Do you know if it was due to the plenum gasket or is this because of the lower intake needing a new gasket?
So let’s say my husband’s truck is idling really hard and jerking/jumping when he goes over about 40mph. Could injectors be the culprit? We’ve taken it to a mechanic twice and they connect the computer to it but can’t find anything wrong.
I'm curious where did you find your replacement injectors? I can't seem to find the ones you show in the video I got a 06 Tundra with 310k miles (with the same V6 engine in the vid and owned it scene it was new) and still running strong amd never lets me down when I need her to work... well until 3 of my injectors went out..(even now the truck refuses to give up) please I need help I've been searching for a while
Good stuff man, I've enjoyed. I believe my 2008 V6 4Runner have pretty much the same engine. I am battling fuel delivery issue @130k miles P0174 BANK 2 and P2238 BANK1 (seems a bit too early for mighty Toyota to have an issues like that, I was hoping for vacuum leak, but rising throttle to 2500 rpm, short trim rise even more on OBDII scanner, lean condition). My plan is to check fuel pressure first and if its sufficient will do what you just show. Thanks for the video. If you reside in my state I will pay you do it bro:)
I just went through this. It was the upstream O2 sensors, both sides. They both burned out within 50-100 of running a fuel system cleaner through. I tried cheap Amazon O2 sensors but the probably remained. Was about to do the injectors but decided to try Denso(OEM) O2 sensors. That did it. Don’t go cheap as the O2 sensors are sensitive. I’d try just one side at a time to see if the respective bank clears up. It’s a 15min job max. Denso sensor was ~$114 on Amazon.
Thank you for reply! Did you have the same error code as I do? P0174 BANK 2 and P2238 BANK1? And you've tried to rise the throttle to over 2k rpm and your short fuel trip did go higher, not lower, right? Because when it goes higher (leaner) it means fuel delivery rather vacuum leak, etc.. I am planning to swap MAF sensor first, and I've already ordered both upstream sensors Denso from Rockauto, similar priced to Amazon.. I am not planning to try any other aftermarket sensors in this case. Only Denso, same that I have now. Also, how did you get these connectors out, such a tight fit especially on driver side.. Appreciate in advance!
I went back and looked and guess the other codes along with P0174 were 2195/2197, not 2238. It was only throwing the code at highway speeds. Changed the pump and MAF with no affect. Was about to do injectors and decided to swap the cheap Amazon knockoff O2 sensors with OEM Denso. That’s all it was for me. Does yours run well otherwise? The connectors are easy. You can do them blind, just find a video that shows where to press. You’ll be able to feel it and then work it out with one hand. I do the driver’s side from underneath, reaching up alongside the exhaust. Passenger side I do from above.
My man, thank you! Yeah, I can feel these connectors, guess I will have to find the way to press on this tub with my thumb.. Also, my rig drives and idles good, I can hear some raspy, unusual sound from either engine or some part of exhaust.. May be from running lean or rich, or may be its not even related.. How many miles do you have and what year your Runner? Its V6 4TH gen, right? or Taco with same engine? Thank you for reading and replies
@@nofear6235 2005 Taco with the 4.0. Same thing really. 240,000 miles though. Little gremlins popping up here and there but once you correct the issue it’s like the truck drives better and better. Previous owner didn’t take care of it at all. Random thought…everyone says you don’t ever have to change the tranny fluid. Pretty sure mine was never done so I figured wth, it’s an oil, they don’t last forever. Did 3 drain and refills. I cannot explain how much better it shifts. Butter
Change that brake fluid! - Yeesh! Excellent video - and real world challenges. Thanks for sharing part numbers. Don't most of these bolts have a specific torque value? (21ft/lbs for the intake plenum, 15ft/lbs for the plenum support bracket, 19ft/lbs for the fuel rail, etc.)

Thank you so much for this video! I changed all 6 injectors today. This video was so helpful.
Thank you-just thank you for keeping a clean engine!
Glad I found this vid, I knew it wasn't a big job but couldn't find step by step anywhere till now. Thankyou

Good, clear video. Thanks for showing us the way, Jabo.
Hey man I think you did a excellent job I have the same motor mine 4.0 v6 2005 SR5 4Runner till this day best vehicle ever owned
Very helpful video! Some dielectric grease on the injector electrical connectors is also good!
May as well do all the electric connectors.
wow once you get the intake off its so much easier to work in and its not that much to take off the intake great video
Excellent video, one of best I've seen! Thank you. The injector holes in the head were very dirty. It would helped to know in advance how to prep the area because it was difficult to clean out...
Thanks this helped me with my 06 4runner, had a misfire on cylinder 6. The hose clips took me the longest its a real pain to get to them.
Was did it end up being you injector
Bigger job than I thought it would be. Thanks for the details.
Good job, really like u naming parts as u work.
So I actually had a retainer fall into the injector port! What are the odds? Luckily I had a Boroscope camera and able to retrieve the clip by putting a dab of grease on tip and stuck it to retainer and pull out like the game of “Operation”!
Thank you for this vid. It helped me alot!
Nice job, greetings from México
You are literally a life saver!!! Thank you for your video!!
cant believe you put that back together with those dirty gloves on specially the gaskets on the intake and throttle body

?

next time pull the fuel pump relay and run it till it dies no more fuel spray when dissembling
I was thinking the same thing!
3 pm great explanation

Why did you do the spark plugs when you had the intake off? Smh

Chris, what does a job like this cost, parts and labor for a 2005 toyota tacoma prerunner v6. I am not to far from your location.
So let’s say my husband’s truck is idling really hard and jerking/jumping when he goes over about 40mph. Could injectors be the culprit? We’ve taken it to a mechanic twice and they connect the computer to it but can’t find anything wrong.
One of my injectors came out with the plastic black piece above the top o-ring. How can I find that or get it replaced? Or will I need a new injector?
Where is the fuel pressure regulator?
I'm curious where did you find your replacement injectors? I can't seem to find the ones you show in the video

Excelent video thank you ❤❤
The 2004 Toyota 4runner has the same engine. Do you know if this is the same procedure for that model?
If has the same engine it should be the same
I'm curious how long was the actual process?
Also, is there a way to just clean the injectors instead of buying new ones?

When I took the manifold off seem like engine oil on gaskets
Where did the oil come from
Blow by. It's normal
How long did it take you to complete?
thank you!!
I hope I can do it I’m only replacing injector number 1
Thank you 🙏🏽
You are welcome
@@JaboTheMechanic did you use refurbished fuel injectors or brand new ones?
Change that brake fluid! - Yeesh! Excellent video - and real world challenges. Thanks for sharing part numbers. Don't most of these bolts have a specific torque value? (21ft/lbs for the intake plenum, 15ft/lbs for the plenum support bracket, 19ft/lbs for the fuel rail, etc.)
but we need to know the fuel trim short term and long term , before and after so we know the numbers
Are these port injection or direct ?
