Im gonna have it looked at next and tested next friday, hopefully it wont blow up before then! I pulled the #4 plug today and found that the gap was fine but the plug was very copper colored and extremely hard to get out (and I did use anti-sieze when I put them in). I put a new one in there and it made it no better, possibly worse. Ugh Well see what the shop says, but it doesn't sound like it will be cheap!
