and that little pulley determines whether the car is sluggish or not, or is that affecting the rough noise

its most likely the cause of the rough noise

nope, just called the idler pulley. and for the sluggishness it could be a number of things...are there any other symptoms?

the best i can say is it does not respond to me pressing the accelerator, it feels like im not pressing accelerator much when it does get going even when foot to floor and it bounces when im going at low speed through towns

and i would like to find engine number to find out if engine was changed

those numbers are way too high for a stock engine. Yes I would like to see the dyno sheet as well. even a 330 doesn't pull that

i don't disagree at all, well a 330 is up to 235hp, a 328 is 190hp, i know that a stock 323i is 170hp,

How long has it been sense you (or someone else) changed the spark plugs?
How long has it been sense you replaced the air filter?
We will start with the simple things first.

thanks, spark plugs changed last week air filter and fuel filter a few months, oil change a few months

Has this lack of hp been going on for a while? Has it been a gradual change or something within the last weeks or months?
I am hoping to keep this thread going so we can get more help. My general automotive knowledge is fairly good. My BWM specific knowledge is not that good.
You are not going to get a gread deal of hp out of a 323.
