is your alero a straight 4 or a V6? and if its a 4 I could give u directions on how to access the waterpump easy, its not as hard though the bolts and nuts suck to get to. As for the idle I have the same prob. When i stop at a red light my car shakes ugly so i put it in neutral to stop it. What could it be? the torque conveter or is it that idle air sensor?
