Mali,
The other post I mentioned wont help you. It just had a picture of the EGR valve to make sure we were talking about the same tubes.
You are probably right about your check engine light, but it could light up for many reasons.
The FAQ section has some info on the recall
here .
I think your cats are probably plugged. Take the recall info to a dealer if your car has less than 80K miles. If it's past 80K, you'll have to pay. It will be cheaper to go somewhere besides the dealer. If your pre-cats are plugged, gut them instead of fixing them. Your car will still pass emission tests if you have a good main cat. Pre-cats are over $1000 to fix. (Not worth it imho)
