Got mine too. Did you do the update ?
Not very intuitive, but I got it done.
I would agree that benx R170 C320 is probably correct, I haven't hooked mine to the Crossfire yet, but I did run it on the 2002 Concorde and it worked fine.
P2404 - possibly the charcoal cannister ( back with the pump and filter ) ?
P1018 - maybe the short runner / long runner flap inside the intake manifold ?
There is a little vacuum line that has caused problems on that for other folks.
