If you're actually serious and can't imagine why I'm giving you a hard
time, think about your communication approach. "Hi, I've got a
(year/model)
Saab, my plugs wore out at x,000 miles and with the new ones my milage has
gone down by an insignificant, meaningless amount. Am I doing anything
wrong here"?

I was actually trying to introduce my problem better. I think there were
tons of posts about "bad gas milleadge".
Going from 25 to 24 MPG is insignificant. A warm day could change
it that much, or tires, or an aftermarket muffler, or any of
a dozen thihgs. 4% isn't all that significant.

So, yeah I expected to find somebody that will say: o, dud, it happened the
same to me last year and this is what I did, or this is what is still
doing....
So you figured badmouthing things you don't understand, and the
documentation provided with the car, was a good way to do that? Odd.

Generic CENTER muffler, this is sometime called SILENCER. I bought it from
the internet, Starla for 87$
The normal muffler is still the original. Also the exhaust smells horibbly..
Any unusual color smoke coming out the exhaust? Or, is it just paint
from the muffler and normal new-muffler stink? You _did_ peel the labels off
of it before installing it, of course?

Crappy muffler.

If the exhaust smells that bad, you either have:

1. Bad fuel quality or...
2. Bad Catalytic converter or...
3. Something generally wrong with the Trionic (enginemanagement).

Cheers!

Ok, finally something contructive...
Yes, I pilled the stikers from the muffler. Now I have filled up the gas
tank with the new Mobile V power fuel (93+ octane - the highest available in
US) + a can of injector cleaner. I have also reset the trip odo and the SID.
Now the SID says 15.5 MPG which it never ever in the worst nightamers would
show, however when I got home (after 10 miles) showed 20.1 mpg, also never
seen before that low...But I will post the final average after this tank (15
galons) and we will see if the SID lies or I am realy screwed....
