We heard you like OBD codes so we added codes to your codes

Yes, I'm a negligent 3rd gen owner. Kinda took her for granted for a while. I promise to earn back her (and your) resect with better service. The truck just enered into the phase of being our only interesting vehicle left to tinker on. Got rid of the self restored 78 FJ40, the turbo porsche, the trackable scion xB, the International Kurbmaster party truck, the DeTomaso Pantera (WTF was I thinking)

But know that this board has been my go-to guide over the last 13 something years for all kinds of deep dive work on this truck, most recently installing a CarPlay head unit, amp, sub and speaker upgrade, with a backup cam, GPS, and secondary camera for atop the trailer. You guys taught me about Tacoma brake upgrades, axle seals, airbags, panhard drop link spacers (don't need that yet) and sundry other awesome tidbits. Haven't contributed back much... But seriously - thank you.

thinkCooper - Nice looking Gen3, with trailer...gotta love the scooped hood.
Is your hood from Toyota or OEM? Like to get one for my 2000 SR5, but fit must be next to perfect.

NGK Wire Set:
Stock # 4412 || Part # RC-TE66 || A8B6 Made in Japan

Plugs:
NGK Iridium IX Spark Plugs BKR5EIX-11 Part # 5464...think gap is 0.044"

That hood is all original from toyota. It's a unusual SR5 5 speed manual, only options missing are the runningboards and the locking e-diff (again, WTF were we thinking). I originally bought this truck for my wife in 2000. She just moved into a lexus F-sport and my brand new (1 week old) Ford Fusion Energi Platinum was creamed by an unisured drunk driver behind the wheel of a freight-liner on the 101 just outside San Francisco. I'm driving the 4runner for commuting until my car is wrapped up.

Got rid of... the turbo porsche, (WTF was I thinking)

Yeah, seriously. I'll take the next Porsche you decide to get rid of okey dokey?

Maybe I'll pick up a used one with 200,000 miles someday, that'd be in my price range lol.

For what its worth I ran the stock wires well into the 200k mile range with zero issues. And if you really want to head these guys freak out tell them I'm still on the original fuel filter at 280k. I almost replaced it when I was searching for my random misfire code but when the fuel injectors came back from a proper cleaning and were almost perfect before hand I found no reason to swap it.

[MENTION=1709]thinkCooper[/MENTION] if the plugs are the only thing you've neglected, I'd say you actually keep up on it a lot better than most guys here [emoji1360]
I'm not a fan of the blue wires- even though they're quality- but [MENTION=95183]octanejunkie[/MENTION] gave great info and links in his post. Since new OEM coils are relatively cheap, I'll assume you'll be doing those too, and I can't wait to hear how much better it runs after new plugs/wires/coils!
That hurts to see that brand new car creamed like that. So, that's not a work vehicle, and you had to use your insurance to have it fixed? [emoji24]

Same coil. No red box.

I've had bad luck with denso part store parts. Just comparing oem to the part store denso you can see a huge difference in quality. Same with the Ford Motorcraft parts from parts store. Had a coil fail in 30k miles and the oems are still going strong at 180k miles.

I just developed a hesitation up long hills. 280k miles on original wires and I'm guessing plugs. Lol. Wonder what it will feel like work new ones.

I agree the blue wires make it look like a wannabe import.

 

[amalik]

Thanks for the offer. I can dig 'em up. Any prefs on plugs? Denso as well?

I use the NGK plugs and wires that [MENTION=10169]TheDurk[/MENTION] recommended to me a while back.

See his post.

Ordered!

I agree with the consensus to change plugs and wires and do your scheduled maintenance. The genuine Toyota wire set with clips is about $45, if you need the clips

Lots of opinion on plugs. I am running NGKs with good success so far, but may opt for Denso plugs on my next tune up

I'd replace the air filter and clean the MAF Sensor at the same time, then drive it to see if your codes clear

FWIW, I had the same P0300 code along with a few cylinder specific codes. I tried plugs and wires, etc, but the codes went away after I found and replaced a faulty coil pack. Process of elimination and scheduled maintenance.

Best of luck

Thank you! - air filter is new, they were replaced at oil changes, MAF sensor was just cleaned after Burningman. Stock wire harness ordered!

Plugs are about the only maintenance item that got shuffled off to dealing with later. Ordered up coils, I figure while it's being working on for wires and plugs, they're easier to replace.

That creamed Ford Fusion Energi is my personal commuter for going to Mountain View from Santa Cruz. Literally had it for less than 500 miles before the drunk CDL driver hit me from behind in SF. He was doing 70, I was doing 50 in a downpour. He then swerved to my left, and in front of me, then spun and took out another car. I managed to not hit him while he was spinning. Luckily I have really good insurance through USAA, they are covering everything, because he was uninsured to boot. Unluckily, the car is as close to a self driving car that Ford produces with lane sensing radar. The left rear radar is on back order, so I'll be two months without the car. Aso luckily, it's a lease. So back to Ford this one will go when it's repaired. Glad I won't own it with this damage history.

 

[thinkCooper]

For chits and giggles - here's a video I shot of driving that 2017 Ford Fusion with it's brilliant adaptive cruise control, heading up to SF for a work related VR event. Irony is, the video was shot about three hours before the return trip and uploaded during the event, and not far from where the driver driver hit me on 101.

The event was a hands on work session with this $55,000 Nokia Ozo camera for capturing Virtual Reality live action. Sweet rig.

Well, I got you beat. I ran the stock wires on my 99 Subaru for 325,000 miles. I also never replaced the wires on my Honda Accord and I put 240,000 on that vehicle. I think wires can often last the life of the vehicle. Spark plugs, NO. Wires are one of those things that aren't that expensive so people often opt to replace them when they replace the spark plugs.

As for the fuel filter, did people like me need to replace it. No, the vehicle was running fine. But, myself and many others firmly believe a fuel filter is not a lifetime part no matter what the manufacturer tells us. Plenty of people have torn apart the fuel filter and have shown the amount of gunk inside. If it was a super expensive part or really hard to replace, I might forego a replacement too. But, it's not expensive and it's really easy to replace. The question is would your engine run better when you're demanding more from it. You might be slightly starving your engine with a partially clogged fuel filter.

We've had this discussion before I believe. Didn't you say you had no experience with Denso parts for Toyotas?

I have had no problems with the Denso parts off Amazon and they have all appeared equal to factory. I have more miles on my replacement O2 sensors than I got out of the factory. The one coil I have is doing fine at 50k. I also have fuel pump and plug boots. I have never seen anyone post on here about bad Denso parts for Toyota.

I will keep using them until I have a reason to change.

IMO, replacing ignition wires is cheap insurance, sort of like "while you in there you might as well" but I agree that plugs are more of a wear item than wires - unless the wires are hella old, jackets dried and cracked or you see sparking in the engine bay in the dark.

I replaced my ignition wires along with the plugs because they were $28 and I was chasing codes. Turned out to be a bad coil, but I'm sure new wires didn't hurt.

If anyone wants my old, factory wires, I'll send them in a USPS flat rate box for the price of shipping :laugh:

Ive owned Japanese cars for over 17 years. I have had denso part store wires, coils, fuel pumps and random sensors fail over the years after replacement on all the vehicles.

I have yet to have any issues with the 3rd gen because I avoid parts store denso parts like the plague.

So maybe denso only makes good stock parts for Toyota's but I highly doubt that.

I'm cut from the same fabric.

While I'm in there, is there anything else I should swapping out?
PCV, etc?

Next longer term maintenance is measuring valve lash and reshimming if needed. Wish I were able to do that at the same time as the plugs but I need to drive the truck in the short term.

I think many of us are in that boat which is why we do "the weekend updates" to keep the trucks rolling

Maybe it was one of the coil packs, the old plugs look way less than 120K miles of use. I'm also speculating that we must have had the plugs changed at some point. Anyway, threw in new plugs, wires, coil packs. It's running solid. Next up? Road test to see if it throws any codes. Plugs inthe picture are:
4/1
5/2
6/3

 

[thinkCooper]

Maybe this was the culprit. #6 plug connector is physically cracked with a hole burned through, as if it were shorting... Whoa. Glad I ordered and installed that "just 'cuz" wires.

 

[Nervo19]

How are your codes now?
