I had the S80 out last week, and it seemed to bog at about 5000 RPMs when I was flooring it in (most noticably) 2nd gear.<P>It would rev smoothly through 1st, then in 2nd it would rev smoothly until it hit about 5k or so on the tach.<P>I tried going off the line, from a roll, with DTSC on and then off, in auto and slapstick mode. Every time got the same result.<P>Any ideas what this could be? <IMG SRC="http://www.swedespeed.com/ubb/confused.gif"><P>

Obviously, it is not the rev limiter (I believe that kicks in at just above 6,000 rpm). You sure it "coughs" at 5,000 rpm and not above that, right? I wonder if it is "just" a software problem<BR>or there is a problem with the fuel delivery under WOT...then you could start looking at fuel pumps, etc. No messages generated inn the message center?<P>Yannis<BR><P>

Nope, no messages, no warning lights, nothing. I mean this car gives you a check engine light when the gas cap isn't tight, so I would agree that it should definitely have some kinda warning message for this kind of thing.<P>I was thinking it might be a fuel delivery problem, or possibly something wrong with the blowoff valve (blowing off boost too soon maybe?).<P>It's my father's car, and I highly doubt he ever runs at WOT, and even if he did he wouldn't notice the little "cough". It definitely got my attention when i took the car for a spin though.<P>
