Sea Foam runs about $4-$7, depending on where you buy it. Wal-world carries it, so do most auto parts stores. Shoot for the bigger can, about the size of a WD-40 can, and dump in a half tank of good, high-octane gas.

Well, I tried pulling the oxygen sensor off (letting it hang by the wires) and spraying it down heavily with a can of carb cleaner ($1.79 from Wal-Mart). I was sure to surround the area with cardboard so the spray would run down to the driveway and not hit anything else in the engine compartment. Used about 1/4 can of carb cleaner using the fine straw on the nozzle and cleaned the sensor out very well. Lots of grime came out!
I put the sensor back in place, disconnected the positive terminal on the battery for a minute, reconected the battery, then started the car. The "Service engine soon" light went out and hasn't come back on yet! I've only driven it a few miles but so far so good!
Now, I do intend to get some Sea Foam (they didn;t have it at my local Wal Mart) and run it through with a half tank of premium gas as recommended, to ensure the other sensors get cleaned up as well.

Thanks everyone for your great ideas!

Sweet! Alcohol or CRC (electronic) contact cleaner are said to be the best, but if the carb cleaner worked for you, then GREAT!

Hope the code / light stays off.
