Mine shoots fire also. Only on the 1-2 shift at ~6600rpm. It started when I got the off-road x-pipe. My mechanic said all the 4.6 cobras run very rich from the factory, especially at high rpm. With no cats to burn up all the extra fuel when you shift, the fuel can get ignited when air gets in their. The only thing that will cure this is to fix the rich mixture using a chip.
