Bring it to an independent garage (prefferably one you know , or has good reputation) and have them scan it to see what's happenning.

Drive it a few hundred miles and see if the readiness codes all set...................IF they don't , then there is a problem , that would most likely need to be diagnosed and repaired before the monitors will set. You don't have a shop in your area you trust , do you?

How many leaves does your scanner have? Maybe you can get a copy of the factory service manual , but I would just drive it 'til the monitors set (that you CAN check with just a simple code reader). Remember , it may be a few hundred miles , depending on driving habits and conditions.

Oak or Maple??... Seriously , could you get your hands on a scanner that will give you 'live' data? That would really help your situation especially trying to knock it out yourself. Even if you got a little 'code reader' to watch the readiness monitor 'status' it would still help. Those run maybe $50.00-$100.00 for one compared to several hundred at minimum for one that reads live data (reliably).
