Default Car Stutters after O2 Sim Install

Ok, I just instaleld the ECG O2 sim to get rid of my CEL 67. Now, under Low throttle (Less than %20) and Low RPM (2300 - 3300) my car starts to Stutter. Its very rhythmatic...like a slow pulse. If I give it more Throttle or get the RPM's above 3300 its smooth as normal. So, does the Secondary O2 affect fuel any? Could the O2 Sim box be 'off' in its calculations that its sending to the ECU?
The car is a 2000 Integra. It ran just fine before I Installed the O2 Simulator. Any Ideas?

The cpu doesn't make adjustments from the secondary o2 readings. If they are unsatisfactory, it will just throw the code (67). I'd check your wiring.

Wiring is ok. I haven't thrown a 67 yet...so Im assuming all the wiring is ok.
