First, thanks to all who responded.
I want to clarify that I don't make this statement as a complaint; other than a slight lope in the idle when the engine is hot, she runs beautifully. It's probable that newer MN-12's (later than my '94) were equipped with different injectors that were quieter, and this may explain why some of you haven't noticed it. While I'm at it, would anyone like to offer a suggestion on why the engine would be lopey at idle (engine hot, in park)? I'd go so far as to say it's the MAF, but there may be a vacuum leak I can't detect with my ears. I will go so far as to say that it has receded with the colder weather (Mass.); this meaning that in the summer, the lope was more noticeable when the engine was still "cold." Take a stab at it...can't hurt. Thx,
-DG-
