When accelerating Cobalt kind of studders. Almost like there is air in the line. Added injection cleaner , so I know it's clean. Maybe I am expecting too much from a 4 cylinder?

I have a 2009 Cobalt. Anyone had this problem, and if so,have any answers ? My driver's side wiper hops across window,then comes back smooth. Tried cleaning window and wiper.Changed wiper,only was as bad if not worse. Happens when soaking wet or dry....annoying! Thanks
