Glad you got it sorted out, sounds like ACS took care of you.

You could be correct on the tach flutter. I like mine as close as I can get it without hitting. Was the replacement you put on a Mopar part? If not, you may try the old one and see if it makes a difference.

It's made by standard flutter seems to have died down it's now minimal and mostly at idle
