Haven't seen this, but I'll try it.  I did notice, just last
night (and it only seems to be the case with the A/C compressor
on) that the engine does *not* want to idle around there.  I
can play with the gas pedal (in neutral) and the engine will run
fine at 800, 900, 1000 rpm, and it also runs fine at, oh, 1700, 1800,
etc; but there's a gap in there where I cannot keep the engine
running nicely at a constant rpm.
