Sound like a loose exhaust. Get it up in the air and check for anything that may be loose.

Sounds like you may have a little back fire when turning engine off,usually means there is and exhaust leak,or blockage in your catilac converter.


Ya that too...

Me and RoweFast thinking alike,

il have both checked up thanks, but the sound is not like a blow back it sounds like something is hitting the body of the car from underneath, its a heavy sound.

Thanks for the above, Sent to to have it checked today, One more thing, The oil light starts to blink from time to time, Than stops, hope thats not anthing major.??


Keeping up with the oil changes is a big plus, to be sure of the oil pressure you get it checked with a mechanical gage, half the time just replacing the oil pressure sending unit takes care of it.
