'93 SSE Model with 118000 mies...

My Bonneville has been running louder than normal, sometimes it sounds like a plane taking off. It hasn't affected power or the way the engine runs, it was just loud in the front. Then today it didn't want to start. Had to turn it over several times before it went and had to gas it to keep it running. Then as I was going down the road it started sputtering and it felt like it just didn't want to go anywhere. It stopped after a few seconds and drove fine...I didn't have any warning lights or chimes...Any Ideas??

well first i would try to pull codes maybe the light went off and you didnt see it check for spark, and check for fuel that will get things off to a good start to get a good diag....

i had the same thing happen to my car and i brought it in a couple days later come to find out the engine was shot

probably bearings...

final death throes of an alternator perhaps?
