My Tacoma was running rough (4 cylinder) and all it needed was a new spark plug so I changed all 4 took 20-30 mins thanks to this video it cost $60 or so because I bought the better plugs at autozone. I appreciate you making this video. I shows the rest of us guys the way and saves us so much time and money. Many many thanks.
CAREFUL not to over tighten that PCV valve, its easy to crack that aluminum. Also, while you have it apart, why not spray some cleaning fluid all over everything, make it look like something was done there. Try some conductive grease on all electrical connections, to prevent corrosion and intermittent shorting. If you're changing the PCV, its time to do the fuel filter too.
The torque for the spark plugs on the 2004, 2.7 liter Tacoma is 15 Ft-Lbs or 180 In-Lbs. Anti seize should ALWAYS be applied to the spark plugs BEFORE installation. Spark plug gap should ALWAYS be verified before installation.
Be careful with anti-seize on spark plugs on some of the imported vehicles. Toyota and Nissan have tech bulletins about not using it as the tolerance does not allow it. While we have used anti-seize for years, we have backed way off when the factory repair manual specifically calls to not use it. @@stevanrose7439
I'm surprised you didn't bother to check the spark plug gaps. I ordered Densos twice now and they have both come with way tighter gap than they're supposed to. They also have the protective plastic. I guess if it runs right its not that big of a deal? And they will increase gap as they age it seems. But personally I will regap all mine correctly.
Why not change out the entire coil instead of just the seal, boot, and spring aside from the cost? Is there any way to tell if the coil itself is still working properly?
Good question. This was basically maintenance and no real repair. We would have had a trouble code for that cylinder misfiring if we had a failed coil. Regarding testing a coil, yes, a couple common ways to test a coil are 1 with a coil tester that lights up when the coil actually fires, or 2, swap a suspected bad coil with a good coil and see if the misfire follows that cylinder. When doing just maintenance, replacing the boot, spring, and seal can make the coil last much longer. Ignition coils have become very cheap in the last few years, especially with very low-cost Chinese-made coils that can be purchased for less than the cost of one single Denso or OEM coil that lasts a decade or more. The low-cost parts work and are very cheap, but rarely perform over the long term like an OEM coil does. So sometimes it's best to help the superior original part last longer.
On this particular engine, those are NOT "coil packs". Those are individual coil on spark plug type coils. My 2000 Tacoma 4x4 with 3RZ engine DOES have the 2 coil packs located right next to each other, at the front passenger side of the engine. One coil pack fires cylinders 1 and 4, while the other coil pack fires cylinders 2 and 3. Personally, I much prefer my pair of coil packs vs these pain in the *ss individual coil-on-spark plug type coils..........although I'm sure many would disagree. With the individual coils for each spark plug, you have TWICE the chance of a coil going bad. Also, there is less to go wrong with the older style pair of actual coil packs. Because oil leaks in the valve cover can cause those coil on spark plug types to fail. The coil packs ( like I have ) can and do fail once in a while........but nowhere near as often........or fail as easily.
I have a 2001 Tacoma 2.7L 4-Cylinder and my spark plugs and coil are on the other side of the engine. The last two are actually underneath and one is behind the throttle body. I think I need to completely remove the throttle body to get to the last two plugs
Whats the Gap on the Original Toyota Spark Plugs, since I’ve recently replaced all four of them and have revs cut at 3500rpms instead of normal cutting. So not sure if it’s a gap issue? Or contribute to a faulty coil pack.
All in all great job ,but next time check your gap the correct way, you can't eyeball a fraction of an inch, lol, that's like you can't tell if somebody's been up in your old lady while you're at work you got to check the gap with your tool lol!!!
Now that I really zoomed in it looks like maybe the thinner end of the tapered spring went in on your replacement. I’m rebuilding my originals and the thinner end is toward the plug. Maybe it doesn’t matter? I’d hate to assemble it all then find out it’s wrong.
@@joef7652 on the 2.7 standard cab they have the fuel line filter next to driver side engine. On the extended cab and quad cab. They located it under the driver which is super easy to do.
I have a 2002 Tacoma 3.4 missing bad, I took one of the coils out and it was covered in oil, I am wondering would that ruin the coil? or can I just get a new boot replacement kit?
I hope you see this because I’m stuck like chuck. I can’t seem to get the new or old spring back on. It’s tapered and that what hold it on. Can’t really tell how you were able to seat it.
Everybody’s saying to check the gap of the spark plugs.. is there not a Toyota specified spark plug that will have the proper gap? New Truck owner here.
Just don’t trust the plugs out of the box it’s better to be sure that they are the same gap this will help with how your motor runs. Add a dab of anti seize to the threads.
My problem is when I put it in gear it takes a long time for it to shift into 3 rd gear. It drags for awhile. Changed spark plug and coil plug in number 2 now it's doing the shifting slow in 3re gear. What do I have to do.
That is wrong! Plugs that have been an engine for a while will have a wider gap. Always, check the gap! On my toyota, I make sure it is 0.032. Sorry but the guy doing this is a "shade tree mechanic." Spend a little money, buy a gauge, and check the plug gaps!
PCV stands for Positive Crankcase Ventilation. On 1960s and earlier cars crankcase oil fumes were vented to the air, thru a small filter. Modern cars route the oil fumes thru the engine to be burned.
I think it is time to trash this truck. It seems that every week there is another problem with it. As commented before, the seals are upside down, check the plug gap, and put anti seize on the plug and PCV valve threads. Shoddy work at best.
Do you happen to know where I could find the correct information about coil pack seal, boots, and springs installation? I've searched through the forums and the coil packs from 2000-2004 seem to be different than other 1st gen Tacomas.
