Changing Symptoms

[hombre@elp.rr.com (John Erickson)]

I've been posting over the last week or so about my 16v cutting out over 4K 
RPM.  Well, in the last day or so, it seemed to be doing much better (all 
the way to 7K), but that was not with a hot engine.  I got stuck in some 
traffic today and the cutting out got much, much worse (as low as 
3K).   The only thing I can think of is one of the temp switches, but its 
OK (mostly) with the temp gauge in the middle.  Its only when it starts 
creeping up that it gets bad (good thing its not summer).   Anyone have any 
similar temp-related experience?
