I purchased a 1999 9-5 4 cyl with 52000 miles on it two weeks ago.
Well, I was on the highway in Sport mode and the Check Engine light
appeared.  The car starts and runs fine.  Is this an emergency?  I'd
prefer to leave it with my mechanic but won't have a few extra days
until next week?  Can it wait that long?

If there are no other indications, I think this might be a "service timer"
(for want of a better phrase) & so might be due for a service. If I remember
correctly, it'll go away eventually, but any Saab garage should be able to
reset it with a tec 2

NO!  The check engine light is never used as a "service soon" indicator.

It is only used when the engine computer detects an emmission related
failure.  The term "emmissions related" can be broadly applied to almost
any engine malfunction.

To the OP>  Have the codes read out to get an idea on what engine
malfunction was detected.  It may be relatively minor, but be early
warning of something more serious.

If you are in the USA, Autozone will read it for free. Findout what
code it is and post the info here. The computer will reset itself
after a certain number of starts (30?) but if the condition that
caused it persists, it will never reset.

FYI - if you have a bad DI cassette you could find yourself stranded
very soon. I would get the code checked.

Many apologies, I didn't intend to mislead, I had a similar snag on a 9-3
about 4 years ago which disappeared after some time. (I did say "I think"
:-) )

Yes, there are a few inconsequential reasons for the Check Engine Lamp
to go off.  One of the most famous (and least consequential) is if you
leave the gas cap loose, or its seal is faulty, you will get an
"evaporative emissions" fault (whatever that code is).

That's the type that disappear after the next fill-up.  ;-)
But how would one know without reading the codes?

Hello,
funny how people always press the button marked "dont press this", and not
check the engine when it says "check engine" ...
:-D

There's a marketing gimmick here somewhere...

check your gas cap.  In Oregon where we're too dumb to pump our own
gas, it used to happen to me often.  I just have to make sure the
attendant screws the cap on properly.  The check engine light could be
just that.  For your sake I hope it is

Well, in NJ the mob is probably running it - or the politicians, which
is kind of the same thing but without the handguns.
