2004 gts 3.8l p0303

So I had a P0306 error code. Took off the Upper Intake, removed the coils, and noticed oil on the spark plugs. Not good....so I replaced the intake manifold gaskets. Replaced the spark plugs, and moved coil 6 to the 1 position. Put it all back together, now i get the code P0303. Moved coil 3 to coil 1 and I am still getting the misfire code for coil 3. Any ideas what I should try besides taking it all apart again and trying different plugs? Am I right in the coil order?


Belt 2 4 6
1 3 5

If I am wrong with that order...maybe I do have a bad coil

If you have a bad coil, the misfire code should follow the bad coil. The next thing you may want to do is replace the valve cover gaskets and spark plug tube seals to prevent oil from gathering on your spark plugs again. Unfortunately this requires removing the upper intake manifold again.

thanks guys. The diagram makes me believe that since i thought #5 was #6 it got placed into the #3. I already replaced the valve cover gasket, so I am good there. But I will have to take off the upper intake manifold again to access #3. I will move #3 to #2 so that I am assured that its the bad coil. Can't work on it till next saturday so I will let you know what I find. Thanks! Wish I woulda researched more before I went at it the first time haha...mixing up 135 with 246 was a setback for sure...Ill let you know what I find.
