Cobalt 4-cyl

  • 165,000 miles
I drove my car around 7:15 am until about 10:00 am. Everything was fine. When I started it up again I heard this loud noise coming from the engine. It sounded like a diesel truck. My flex pipe was disconnected. This attached to the manifold. I didn't hit anything to cause this problem. I asked the repair man what could have caused it and he didn't have an answer.
