That's the "heat shield rattle"—a common problem, your dealer can tweak the shape of the heat shield a bit to eliminate it. (It probably continues in stealth because the engine doesn't shut off immediately: once you've turned it on, the computer tries to keep it running until it has warmed up properly, to avoid moisture condensation issues.)Michael said:Hi,
My karma has 6.28, new batteriers and fan, built nr around 2000 so its if fairly new.
I noticed this.
When you floor the gaspedal and running from stealth everything sounds ok.
When you change to sport it comes after a while at full accelartion, it sounds like a garbage disposal(rattle sound) right under the driver och passerenger seat.
When I flip over to stealth the same sound can be heard which is strange.(not as loud but still)
It is only when you floor the gaspedal.
Is this normal?
My karma has only done 1280miles
I should probably have mine tweaked, it buzzes a bit sometimes.
