I had a misfiring on my car recently. Turned out the injector harness on the driver's side rear cylinder was suffering from a bad connection. Literally jiggled the wire while idling and heard the engine smooth out (I must have knocked it loose when changing plugs and coil packs). You can spray a little wd-40 on the contacts and check them all. Take 2 mins and worth a try. Doubt it'll help but..
