lack of power and strange noise.
 

Hi guys im new to this forum and hope you guys can help me. I have just bought an 02 coupe and am having a little trouble with it, firstly my car is quite slow and lacks power, i thought these things had close to 140 bhp also the car takes a long time to drop the revs meaning the i end up over reving when changing dears, and finally there comes a squeal or sort of whistling noise from the engine when reved under load, but only under load u can rev it when not moving and it is fine n( albeit still very slow to drop back to idle ) the noise corresponts perfectly to the movement of the torque clock in the instrument cluster, pleaseeeeeeeee help if you can as i really like the look and feel of this car and dont want to get rid of it just yet.
