Default Pinging, died, now misfire on 6

Last I drove my 06 3.7 ST it made about 8 miles and started pinging... I pulled over and it died. Would not start. Got her towed home and checked it started but very bad idle. Check engine light flashing. I changed spark plugs, coils, cleaned all the injectors and the rail, even changed out the crank case position sensor. Still same problem. Ideas??
