- Well I was planning on taking a trip to go shooting, but ALAS, my engine decided it had other plans.
For those of you who are interested, this is how to diagnose a Misfire and change the spark plugs and coil for a 2005 Toyota Tundra 4.7L V8.
Not my normal kind of video, but it can definitely help you save money if you need to work on your own truck!

Before you buy new coils. Make sure you check the coil end that contacts the spark plug. There is a spring inside that can break off and fall out. Not a big deal. Find another small spring. Bend the end of it out so that it can hold inside the coil wothout falling out. It helps to remove the rubber boot on the end.
Hope this helps!
After biting the bullet and replacing the coil then seeing your post, what you described was likely the quick fix for me. I didn't have a small spring handy anyways but appreciate your insight. Especially when I need in a bind roadside someday which we all most certainly will have. btw let's say I was roadside... do you think I could rig it with something other than an actual spring and get myself home? just curious just in case :-) thanks again for good quick fix tip.
Don't buy ANY other coils than Denso. It's what Toyota specs them with. The others will always be cheap Chinese knock offs.
I just replaced 7 out of 8 of my coil packs on my 2006 Tundra double cab, because they were cracked bad. Not a hard job, but very expensive! Good video, and keep that Tundra going.
2007 tundra 5.7 getting p0300 missfire 2 and 4. I know the spark plugs are only like 20k miles old because they were changed when i installed the trd supercharger. Truck is reaching 90k miles. This video is very very good help to me. I had already checked the spark plugs and gap and those all seemed good except one was a tiny off .033 of .031 (yes true superchargered vehicles have a different gap) but im sure that isnt it. Im seriously thinking maybe a couple coils wow thatd be a cheap simple fix. Im wondering if i can ohm it out and what the continuity should be
When I last changed my spark plugs, all but one ignition coil were good. Now today, my truck started misfiring and I freaked out. Got home without much hassle, plug in the scanner, and it reads that cylinder 5 is misfiring. I then remember that is the exact same ignition coil that I noticed was going bad but was too cheap to replace it. Pull it out, put it on cylinder 1, erased the code, then cylinder 1 is now misfiring so I know exactly the issue. Lesson learned lol. Oh god good thing it misfired in the parking lot of my local Home Depot. It would’ve sucked if it misfired when I sometimes go to San Francisco for work.
You will swear the transmission is dying....
An engine light, on constantly, means there's an issue that you should fix but a blinking engine light means a misfire. When you see that it's almost always a coil. When you see the blinking engine light pull into the advance/Reilly's/zone and have them connect their obd2 scan reader. It will tell you where the bad coil is and you swap it out. $120 for Denso coils.
Don't use worldpac.... always use Denso on your tundra/sequoia. Its what's meant to be in our Toyota's. Everything else is junk and fails when you don't need it to. Original spec denso coils normally see 100k life cycles. I had worldpac fail in a month.
If only they made changing the oil this easy.
? It is
How did you know which coil was bad?
Cory WILCOX the code the engine gives you indicates which coil died I believe.
What was the code that came up
Life's a Joke oof, it’s been a long time, but it was a P03- - code; the last two digits are based on which coil.
hope u dont change the starter on that thing, its a pain.
That was like a side quest.
Basically it was! 😃
