Yes, as to the plugs, I suspected the same so I actually I just replaced the plugs 2 months ago. They are brand new Bosh Platinum +2 plugs. This seemed to help the situation some, but did not eliminate the problem.
Aside from running LUCUS through the system, I have not done any carbon build-up cleaning. I was considering running some seafoam through the system. (A friend swears by the stuff)
No CEL is lit. However, when I had similar problems with my Maxima, it ended up being the MAF, and it never lit either. That MAF ended up getting replaced, and it was a Night/Day difference.
I do not have a fuel pressure guage available. Being a shadetree mechanic, how difficult is it to hook up and use one of those?
Thanks for the reply and suggestion.
