I have a 2001 Mustang 3.8 v6. I have rebuilt the engine and for the most part it is running great. I am getting an intermittent misfire on cylinder 2 and 6. I replaced the coil pack becuase it appears to have arc lines at the bottom right under the 2/6 coil. However it didnt fix the problem it did seem to improve some though. Can the cam synchronizer not being in perfectly cause a mis fire on just those cylinders? I think I may be off slight on the cam sync. Those are now the only 2 codes I am getting, I was getting a p1309 but after moving the cam sync that has not popped the last couple days just p0302 and p0306.
