also, what the hell is limp mode....
yes there are two o2 sensors.. and yes you can do this yourself, jack up your car they're attached to your exhaust, on the catalytic converter if I remember correctly. Your CEL code should specify which o2 needs to be replaced. All you need is a 7/8 in wrench to remove it.

Limp Mode is a default set of values stored in the ECU non volatile memory. If the ECU senses a sensor value missing or out of programmed range, the CEL will illuminate and the ECU will shift to these values to allow the engine to run at reduced power to "limp" to a service facility without further damage to the engine.

Depending on the engineered values and type of engine, the limp mode can enrichen the mixture, change the timing curve, limit boost, etc. The ECU should remain in limp mode with values locked until all signals are again received within the programmed ranges and the CEL will extinguish.

you should also check the connections to these sensors... have you tried resetting the ecu from its codes? (taking out the ecu fuse and leaving it out for about 15-20 minutes)
