I wish I could get a good video on here of my shifter vibrating at idle. I dunno if it's SUPPOSED to vibrate, but the only vehicle I've ever owned before that did had a 4 bbl 327 chev... and it was about 40 years old...
I first noticed it a couple months ago that when I pop it into neutral to coast or slow down it'll idle smooth for a while at around 650-700 rpm but if I get to a stop light and sit still within about 10 seconds it'll drop to 500 rpm and the gear shifter will do this little shimmy shake every couple seconds. I've listened to it just sitting in the garage idling and it doesn't sound any different when it does it but holy crap can you feel it on the shifter.
So my question is... what's up with that?!
