Hello!I just bought a 1998 malibu with a 3,1L and 135000km on it.The engines runs fine but there is a rattle noise in the a/c pulley area that come on and off when i put the a/c or the fan heater on.It happens a few time when i slow down the engine dies but start right up again.The gas tank has a rust hole in it,so i assume that the fuel filter must be clogged.The rear suspension make a loud noise too when i hit a bump,like something is loose underthere.Strangly the car is very smooth on highway,where the pavement have no hole in it.Since i'm new to GM cars,can anyone help me on this,to pinpoint the probs,so i don't get rip off the next time i go to the garage?Thanks a lot!

You definitely need a new A/C clutch. With the engine off grab the clutch and wiggle it around with your hand. The sound will sound the same as when your engine is running. The reason why the noise comes and goes with the A/C on is cause your clutch engages and disengages as pressure in your A/C system increases and decreases.
