Anyone having a LOT of car engine problems? / Gas Quality?

Yes, a lot of problems are being caused by the additives in the gasoline nowadays. The ethanol they put in the gas is making the cars run hotter, therefore creating problems internally with carbon build-up. Like the guy above me advised, get a bottle of Seafoam, (you can get it at your local auto parts store), and read the back of the can to follow directions. This should help a little.
