Those codes all point to fuel ratio issues. If all the codes started popping up after washing down the engine(?), then I'd suspect one or more of the plugs on the fuel/air system are grounding or faulting due to moisture (TPS, MAF, MAS, etc). The thread I've noted above ended up being a product of mud on the MAF. A few cleanings and it was fine - though it could have been cured by the connector drying during the process of cleaning. I know there's no specific advice here. But those are some areas to check. Hope that helps...
