I have what I think is a slight miss.
I'm going to try and get hooked up to an AE soon.

Here's a video of it what do you guys think. The vibration is the exhaust against the frame I fix that but it is perfectly synchronized with the missing the engine.

2nd video is set to private.

I would change out that BW CPS with a Ford one before you get too worked up...

Once you get it on an AE look at cylinder contribution. Could be an injector going bad, or coming loose etc...

The best video for demonstrating vibration would be a glass of water in the vid.

Its not bad enough that you would notice it in a glass. Its more noise than vibration. There is an obvious (by sound) change in vibration every few seconds.

I stand corrected. That's actually showing it a bit... Give me a minute to upload it.

Still doesnt show it super well... Like I said, its mostly auditory, which is most apparent in the first video when the exhaust was rubbing.

Hum...my truck shakes quite a bit at idle to the point where it's hard to use the laptop on the center console.

No bio lately. Not in a long time.

Oh? You might start a thread on that, if you don't get some good ideas from this one.

I've got the AE in hand.

What tests, and values should I monitor/record?

I ran CCT and all it came up with was the AIH code, which is fine its deleted.

Rotational Velocity was 0-1.4 on all cylinders, even #8. Mostly below 1.0.

This is with an OEM Black CPS
