a short squeal when start accelerating
hi guys,
its been a while than when i start accelerating the i feel a little shake and at the same time hear a short squeal.
*it wont happen if i rev the car when gearbox in P or N.
*it will happen only when start accelerating from standing or very slow cruising speed (up to 10-20 KMH).
*this squeal is very short, like 0.5 sec.
the fact that cannot hear it when car is in P or N, and the fact it followed by a gentle shake makes me think it might be related to the supercharger, maybe a bearing or something like that.
anyone knows what im talking about and can guide me?
many thanks!

Sounds like it's the infamous supercharger "chirp." I have it to but learned to ignore it...
Are you talking about a shake or a slight hesitation..mine used to do it but after I replaced my CPS and IC pump it has gone away for the most part but occasionally it will do it when it's cold..

Crank position sensor, when it goes bad your car will die after about 30 mins of driving. Then start after cooling down, easy to replace yourself.
