Hello,

after having missfires in my GC 6.1 SRT8 2008 I changed spark plugs, ignition coils and fuel injectors. The orange engine lamp was still on so I tried to erase the DTC's but it did not work. When I hit the button "erase" and reload DTC's, the codes are still there: P0300 missfires and some other codes here not important. So I rewrote the configuration, hoping that this would erase the history which it did not. When I ran the scan and added missfire to be monitored, it showed no missfires and no history in missfires. But the engine lamp is still on. Where am I wrong? Thank you!
