I'm getting the same 2 rich error codes using a standard OBDII on my '02 3.0. Yes, taking it to the dealer or indie shop is one solution but I'm trying to figure it out and fix it myself so that's not really helpful advise, more of a Captain Obvious response and not what a forum is about IMHO.

Doubtful its a vacuum leak as that is a lean situation not rich. If anyone is getting these error codes with a standard reader and have found a cause, please share!
