So I have a '08 Cobalt la 2.2L and I have been trying to pin down a misfire in cyl 1, I've already put in new plugs, coil, and injector, and still have the same misfire. I had it hooked up to a scanner and it seem that it only happens under 3k rpm so I'm not sure what else could be the problem. Any advice from anyone with the same issue.
