I have an 87 Westy (2.1l). The last 2 days it has been exhibiting an
extremely low idle at cold startup. It will fire up quickly, which is
normal, but then will idle way low, like 300 RPM. Just barely hanging
on, so to speak. If I give it gas it will respond, though it seems like
it runs a little rough. Sometimes it'll clear up as soon as I give it
throttle and then it'll idle correctly. Other times it takes a minute.
But in all cases it corrects itself seemingly as the engine gets warmed
up and runs fine from then on.

I searched the archive and there's an exact description of this from
about a year ago. The suggestions from listers at that time was to
replace the Temp II sensor. I'm unable, at this point in time, to find
out whether or not that cured the problem.

Any input/advice from the community would be appreciated.

Thanks,
-Roger
