2005 Chevy Impala that sputters under heavy acceleration/load. Throwing code misfire 6th cylinder. My thought was spark plugs, changed them. Still threw the code. The idiot light also will flash but if you lay off the gas and sorta feather it the light will stop flashing. Most times it is north of 40 mph that the light will kick on and flash but it will also sputter under 40 mph. I am now thinking coil or mass air flow. However I could be missing something and wanted another opinion or ideas.
