ok, ima give some more insight to hopefully find a solution for this problem. on the first sensor, as soon as i reset the ecu it would immediately throw the code. now with the new sensor, it waits about 3-5 seconds then shows up sayin the same code 65. heres a thought i just had. what are the signs of a cat goin bad? i have a catco hi flo cat(on there since july 04) BUT, i did notice somewhat of a sulfar smell sometimes under somewhat heavy acceleration, and i did also notice a rattling sound between 2500 - 3000 rpms. could a potentailly bad cat cause this code to come up?

The rattling may be due to the welds for the heatshield coming loose on the cat.
What brand sensor was used?
Was the ECU reset?
Here's some info from team-integra that may or may not be your problem.

The oxygen sensor measures the amount of oxygen present in the exhaust gas. Depending on the voltage generated by the oxygen sensor, the engine management system will change the air/fuel ratio to obtain the desired oxygen level present in the exhaust gas. A malfunctioning oxygen sensor sending an erroneous reading to the engine control system can cause a too rich or too lean condition. A rich condition will cause the converter to overheat and melt down from the unburned fuel being ignited while a lean condition can result in a misfire that can lead to the same result. Oxygen sensors wear out and need to be changed per your auto manufacturers time and mileage limits.

i used an oem sensor, and reset the ecu, but it acts differently with this new sensor in. with the old sensor, after i reset the ecu and restarted the car it would immediately pop a CEL light. with this new one it waits a good 3-5 seconds to pop the code.

It's possible that there is something wrong with your cat then, and the sensor is reading something that the ECU doesn't like and throwing a code. The two oxygen sensors work together, so there is something happening between the first and 2nd sensor.

I read somewhere that a blown alternator fuse could set off that CEL :dunno:
You should ditch it for a Carsound converter, they flow better then Catco converters.
