I recently replaced my valve-cover gaskets because I had a cylinder misfire CEL and I had oil on my plugs. I've alsocleaned the plugs. Well, I've since put 200 miles on the car and the light is gone. However, the stuttering persists. (I'm pretty sure it's a misfire). I haven't changed the plugs yet, but I plan to change them tomorrow. Is there anything else I should consider when trying to diagnose this issue? Thanks for any help in advance.
