O2 simulators can be purchased here http://www.o2simulator.com/
You can't run a simulator in place of the front o2's because the ECU needs accurate oxygen readings from them to correctly maintain your air fuel ratios. The simulators are generally used for the rear o2's when a cat is taken out of the exhaust system. That keeps the ECU "thinking" O2's are still there so no CEL comes on.

He's talking about the rear 02 simulator. There's no such thing for the front o2 as the ecu uses them to control the engine. The rear o2 just sends a voltage to the ecu and does not influence any engine parameters.
