vacuum leaks, stuck or leaky egr valve, leaking intake, bad valves, ect

you most likely need an alignment or your tires just need to be balanced
my 1990 300zx is idling rough what could cause this?
Something can be taxing the work of the alternator, or the alternator can be weak and needs replaced.
It may have worn spark plugs and or bad spark plug wires, time for a good tune up.
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
NO... You need to check for a vacuum leak. We would be able to help you more if WE new the year.
The fuel filter would not be clogged. Running completely out of gas would cause air to get into the fuel line causing some performance issues.
it might be your egr valve. there is most likely a little piece of crud or carbon stopping the valve from closing all the way this causes a rough idle. 20 minute fix at a shop.
I would suggest a new set of plug wires.
i would like to know what would cause the miss firing in Chevy Malibu
the radiotor or the cams
