I followed the PCV line tonight, even used a mirror to view the bottom,.... "looks" okay.
However, I followed the instructions in that link to clean the MAF sensor, and found the inlet side of the probes covered in "fuzzies". This seems very promising.
I cleared my codes, but won't be able to test drive it until tomorrow. (Amazing how a small cutting disk on a Dremel tool can turn those Tamperproof Torque screws into flat head screews)!
I very much appreciate everyones efforts in posting ideas. I will certainly let you know how the story ends.
