Usually, the P0605 comes up when a truck's scanned with a tuner/programmer/or chip plugged in. As for your hard starting, try unplugging the DP to see if it clears up any just to see if the problem goes away. If it starts the same, you've eliminated the DP as being the culprit, if not, call Jody or run some diags with a good scan tool.
