Unsteady idle

[MedTech]

Hi all
I have a '21 BSBB and an intermittent issue has been popping up with the idle. This issue is not happening often enough to be able to take it to the dealer, under the extended warranty, for it to be likely for the dealer to duplicate or see the problem however I did get a small video of it and posted it here. I wanted to see if anyone else has seen this with their BS before I contact the dealer.

In the video, you will see the RPM, at idle, suddenly drops and when the idle drops the whole vehicle lightly shakes. At this time I am sitting either in Park or in Neutral and the climate control system is not on, I have also seen this occur when the vehicle is fully warmed up and when the engine is cold at the first startup of the day. I have never felt any idle issues while the vehicle is in gear.

If anyone has seen this on their BS or if anyone here is a service tech for Ford and know what the issue is, it would much appreciated if you can give me some ideas.

Thanks.

Is it correlated with filling up? I had this on another Ford but only after a filling up with new gas.

If you have it on video, take that to a dealer and ply it to the service rep. He may ask for a copy to give to the technician.

Worth a try.

No, it did not correlate with filling the tank. I had it happen a couple of times when leaving work, once in the drive-thru and this past Saturday it did actually happen leaving the gas station.

My plan was to send the video to my service writer and see if he can show it to tech but I don't think this is too promising if they cannot duplicate the problem.

Private message sent (I think). Please let me know if you don't see it. Thank you.
