UPDATE 7/23/08:

I read in another thread that CRC's MAF Cleaner spray helped resolve a similar issue for another member. I'm not usually a subscriber to the "repair-in-a-bottle" philosophy, but I figured it was only a few bux and a few minutes. Well, I disassembled the MAF and sprayed the everloving crap out of it (being careful not to touch the delicate bits). I cleaned the intake temp sensor too. Reassembled the whole mess and fired it up - - the problem persisted with no change accept for a possible improvement in smoothness as I transition from off-throttle to on-throttle.

Tried some fuel-injector cleaner too - no observable difference except for a lighter wallet...

Troubleshooting will continue...

By the way, I tried to hook up an OBD-II diagnostic system (AutoEnginuity) to the OBD-II port in the passenger footwell. The software would not make a connection to the car's ECU - and I can't figure out why... ...I know there's a raging debate regarding whether or not a 1995 maxima is OBD-I or II, but I've got an OBD-II port, so I'd assume that means the car is OBD-II equipped....

Anyway - still only getting the 0505 code

Any thoughts would be appreciated! Again - I intend to post up the solution when (if) I finally find it!
