First thing you need to do is have the codes read, Autozone does it free, Post the results with the code number(s). Even if the service engine light is not on, there should be freeze frame data stored.

I had my '01 windstar tuned up at a 100,000 and then my check engine light came on. It ended up being a upper intake valve leak

Those are 02 sensors codes, Bank1 sensor2 and bank 1 sensor3, make sure the connectors are tight, and no oil or grease is on them.
