I have no practical experiance on this american vehicle but if the O2 codes are coming up then its possible that one of the sensors has come loose and fallen out ,but if you had it looked at by a garage somewhere and they said to replace the whole exhaust then something is amiss here and without a my head under the car i couldnt tell you from afar ,either the garage is after a easy job with a good profit margin or its fallen apart so i would advise that you ask another mechanic to have a look for you

Popping sounds thru mufflers/smell of fuel


Run the fault codes and replace faulty units as it sounds as if you have an over fuelling problem.

Have a 2007 freestar thats has a popping noise out of the throttle body thats sounds like popcorn popping. doesn't affect it running though.


its your mass air flow sensor. the air filter housing does not seal well, wich causes dirt and turbulance to (MASF). So your vehicle will begin to run richer, making a popping noise. then the vehicle will start to jump while driving or even stall.
