Fill you gas tank up with some good quality regular gas. Put 4 ounces of Marvel Mystery Oil in a full tank. You will know it’s working when you can no longer hear your fuel pump, while waiting for you check engine light to go out. It will also clear up your fuel injectors. Let me know if you notice a difference.

Don’t recommend running higher octane in a stock 99 Civic. If I remember right, you should be running 87 octane. Around here that is “regular”, so I never look at the number.

Here is a better test. When your sitting in your car, and all is quiet. Turn on you ignition till the check engine light comes on, but don’t start the car. Wait till the check engine light goes off. Did you hear the fuel pump wind up under the back seat? Now start the car. Did it fire right up?

While reading your post, I was thinking wire harness. See that at the end, you are thinking that too. I would double check all your wires from your ecu.

1990 Accord
My Honda service manual says to use anti-seize on the spark plugs.
At the dealership, did you guys use anti-seize on the spark plugs?

Would like a link to the NGK docs you where talking about in the video.

Thanks for the video

That’s a nice motor. The D16Y7 crack at the exhaust manifold, which causes lots of strange problems. D16Y8, they moved the catalytic converter, under the car, so they are less prone to the exhaust manifold cracking.
