I just got this westy, and it just started this weird idle pattern.
After warming up, it will settle into a "rhythm", like this.It will idle
at ~800 (I have to figure out how to connect my gage to this rig.battery
in front and all, so this is my calibrated ears estimate), then will
search up to perhaps ~1200-1500, then will drop (quick drop) to ~600
rpm.then the cycle repeats.  Perhaps 5 of these cycles per minute.

Any thoughts?  This is my first fuel injected engine, perhaps is related
to that?

Thanks in advance
