Dmax Mav has you on the right track here, but jumping to conclusions it sure sounds like a cracked injector(s) issue. Thing is, I'd expect more volume in the crankcase.

I'd check system restriction first. Could be another loaded/plugged fuuel filter. The fuel system restriction is the first place to start with 1093 and 0087 diagnosis, and rather than just changing teh filter I would suggest that you test restriction to see what it is. A filter can load up VERY quickly with a bad tank of fuel. and put you right back to square one.
