I changed the plugs and it still fills like its missing can ibe the coil or the injector and how can I fix the prob? Will adding injector cleaner to the gas tank work?

Hello,

Since it is misfiring on the #2 cylinder try moving the coil to another plug if the misfire moves then change coil.

Post Findings.
