well it all started when i was driving on the highway and suddenly the car stared slowing down and when i tried to give it gas it started backfiring. I pulled over and it was idling just fine but as soon as i went to give it gas it started backfiring and wanted 2 die. After a few minutes of idling it was fine and i drove off. It happened again after another half hour or so of highway driving. Then same result and ran fine. later that night i went 2 start it and it struggled but finally went to idle and was fine. Now car doesnt start at all. Just cranks untill i changed the fuel filter which had almost a rust tone 2 the fuel that came out of it. now it almost starts but still doesnt. I just bought the car a few ago. I changed oil, oil filter, spark plugs, intake filter, and added fuel system cleaner to many to many fuel tanks.
