2009 Nissan Versa changing spark plugs
I just changed the spark plugs in my 2009 Versa sedan. I replace the plug with the same brand and model that came out. After re-assembling everything, the engine doesn't run smoothly. If it were an older car, I'd replace the points. But this thing doesn't have any. Anyone ever run into such a problem? If so, what was your solution. There was no noticeable problem removing or replacing them. I also changed oil, oil filer, air filter.
