Updated: I finally got my supercharge belt replace today, and I am happy to report the problem seems resolve. It has been almost been another 18K on my card and the problem never really seems go aways, does not really matter what I did to the car until I finally decide to change the belt.
I just pick up the car and driving back to work, the car seems pull a little bit harder and a little bit more response after the belt replace.
I am keeping my finger cross that is the solution for my problem.
Updated: it has been a week since I replaced the supercharge belt and the car still run fine - almost like new, pulling strong after 2000rpm - the sluggish problem now is gone. Happy motoring again.
Enough time for the placebo effect to have worn off (I've had a few fixes that I was sure fixed it turn out to be just my imagination).
Thanks!
I'll do this asap.
the MPG is almost identical 26.7 (before and after it start to have the sluggish problem). It has been two weeks after the belt changed and it still get the same mpg 26.7.
Spring and fall, many mini's have temporary performance issues....they seem to be assocated with the yearly changeover in fuel from winter to sumer+ visversa (done for vapor pressure). After 2-3 tanks, the computers seem to adapt....and return to normal.
Since some non daily driver mini's take 2 months to use up a tank of gas...some folks have the issue for a long time....

That happens to a lot of people, but this particular thead deals with a longer term issue.
A select group of us have had this problem for a very very long time.
Every day for years in some cases - I myself have spent lots of $ going back more than a year...this is not your average bad fuel issue...or "dip at 3000 rpm that all mini's have"...it is an extremely annoying problem that gets worse as time goes by.

Reason: Problem first occured just more than a year ago, not 2 years.
I bought some Prestone Belt Dressing and gave the belt a nice working over yesterday.
Today the problem is gone. I'll give it a week for the placebo effect to wear off and then report back.
I checked my maintenance log - I started replacing fuel filters, coil, spark-plug wires, plugs, doing Seafoam, BG44K, PCV valve etc etc...2 months after replacing my serpentine belt!
I used a Dunlop replacement belt, not an OEM one...and yes, looks like my troubles started shortly after...

I think I am having this same problem. More details and hopefully a video to come, but how do you differentiate between an issue with the bypass valve (BPV) and the supercharger belt in terms of symptoms? Any technical explanation someone can provide would be greatly appreciated.

Yes I am having the same problems mentioned in this thread. My car is a 2002 and has 176xxx miles, so I'm sure some of the problems are from age on the engine internals. I just spent $420 to replace the oxygen sensor and I still notice my car hesitating from 1000rpm-3500rpm (along with a strange high pitched whistling noise coming from the engine). I will try to zip tie the BPV today and I plan on buying some BG 44K to see if that does anything. I dont really have the money to replace the supercharger belt so hopefully so hopefully that is not it.
