idle surge

["Robert Strause" <rdstrause@domain.elided>]

Hi folks,

Question for you all re: my '91 Spider.  It runs great.  It does something
annoying though in that it surges at idle.  When cold, it idles relatively
smoothly at 1k.  Once warm though it falls from 1k to 500 and oscillates
back and forth.  Never stalls, but threatens to now and then.  Its annoying
as heck, especially when stopped at a light and other drivers look at you as
if your cars falling apart.  Mechanic says its normal for a fuel injected
Spider, but I don't believe it.

Anyone no otherwise ?

Thanks,
Rob
