OK, now that I have your attention- and thank you very much...my wife's car has some "major" issues!!!
1998 V70 GLT, 164K, hers since 99K, no abuse to speak of....

I endured some 45 minutes of stop and go (SlOW!) trafic due to the snow here in New England and shopping madness- so I had some tire spining....
When we got to plaza the car was weak, minimal power, she then stalled out, but I got her up and running and found parking spot- with more stalling, but we got her in.....thought I would have to push it, so wifey backed it in-and I am pretty certain that I saw some black smoke from the exhaust, and then there was that nasty "rotten eggs" smell- hhhmmm??!!??
Well we shopped quite a bit and she cooled off, we had no phone-a-friends avail on Saturday nite, so we prayed for miracle and drove it home- no problem!!!
Just out of curiousity I drove it Sunday morning, yep, a power loss followed by stalling.....
It has a new cap/rotor/wires just 3 weeks ago, and no codes were present...

I know, I know- it can be an array of things, but maybe someone has experienced these symptoms??!!??
Might this be turbo/exhaust/ catalytic issue- is there correlation??


Many thanks- Mike!
