2008 Mustang Shaking
I've noticed that when i say stop at a red light my 2008 4.0L V6 with automatic transmission seems to idle fine for about a minute or so and then it seems to vibrate or shake more than it was. Also while driving it seems to shake a little too especially now that the weather is getting warmer.
Any suggestions?

Is your idle speed fluctuating?
I'd start with a good TB cleaning, fuel filter replacement and then run 1 or 2 tanks with SeaFoam just to rule out a dirt/buildup issue. Then begin with the more expensive troubleshooting if those don't work.

That's true. Now that I think about it, the 4.0 doesn't have a gasket for the TB, just an O-ring that's pre-installed in the TB and doesn't get removed
