NEED HELP!!!

I'm driving a Preve Exective Manual. I'm glad that i bought this car and enjoy the ride so much so far.

However, recently i found out that it start to develop some noise especially when i release the clutch at 1st gear.
Noise is heard coming from the back then to the middle of the car. It comes to me like the fuel pump is suffering is sucking the fuel in and instead sucking in the air that makes the noise. ohmy.gif

Another thing is when driving in heavy traffic, the car seems to be "shivering" whenever it comes to a stop. ohmy.gif
Anyone has come across this problem so far? Please help!!!
