I changed my plugs and plugwires recently and the damn check engine light came on. So I redid everything to make sure it was right and it was. I used an OBDII computer to see what the computer thought was wrong. The computer claims I have a misfire and am running rich in cylinder 7. Any ideas what might be causing it? I don't think it's the fuel system, but I wouldn't discount it just yet. Any help would be appreciated.
