Can anyone plz help me! i'm clueless here! Anyways, i have a '02 Altima SE with the 3.5 ltr V6. Motor has about 109,xxx miles on it. About 1 week ago, the car started to make a fluttering noise from the engine. you can hear it pretty good from inside the cabin and when you first start the car up. don't know what could be causing this. i know my sprocket/crank by the oil filter is wobbling a bit. could that be making the sound? is that suppose to be wobbling? any help would be nice!!!!
