Ivan’s diagnostics are always top notch — he really explains everything in a way that makes sense. Thanks for posting the final part, I’ll definitely go back and catch the first two.

You can't beat OEM reliability, especially on Toyotas. Thanks for sharing the whole process!

Not just OEM, but buy from a reputable dealer. DO NOT buy stuff like spark plugs and coil packs on Amazon or Ebay. All too many of those are fakes - counterfeit merchandise. I found that out the hard way when I bought spark plugs for my pickup on Ebay. Ad said they were "Genuine OEM Motorcraft" and they came in boxes that sure looked authentic and so did the spark plugs inside. They MELTED DOWN in less than a thousand miles of driving. There's many YouTube videos out there talking about this problem of counterfeit parts being sold as "genuine OEM". NGK even has a video out explaining the difference between spark plugs made in their factory and the counterfeits out there that are marked NGK.

Funny, when i replaced the coil packs with DENSOs and put the proper dual strap plugs in, it woke up the 5VZ. Prior owners had used whatever they found and single strap plugs. The engine bay even has a dual strap plug decal in it. DOH!

OEM for sure!
