Your truck is not OBDII and only has 1 O2 sensor. Your idle problem is probabaly due to a dirty IAC or a vacuum leak. The computer doesn't care if you have cats and a full exhaust or open headers, as long as the O2 sensor is inline and connected.

The downstream O2 sensor only monitors catalyst efficiency and has nothing to do with engine fuel control so a simulator won't affect how the engine runs. As stated above, this is the only O2 sensor the simulators are meant to replace. A simulator will cause the engine to run incorrectly if installed in place of the upstream O2 sensor(s).
