Each time I check the plugs I find that the trailing plugs are very oily. If I tap them on my hand I get quite a bit of liquid out. The leading plugs are also wet, but not oily.

 
Where's all the oil coming from?  Was the engine assembled with more than the average amount of goo, or maybe stored with some sort of oil for protection?  Wet, oily plugs aren't going to fire well, if at all, so that's got to be part of the problem. 
 
Try removing the plugs, turning off the engine computer, and crank the engine over enough to blow some of that crap out.  Next install NEW (not cleaned) plugs and give it another try.   
 
Good luck.
