check the wires. they may be unplugged.

 

Your O2 sensor is working fine.

Code 67- Catalyst System Efficiency below threshold

Straight pipe will give you that code.

 

strange, when i searched. alot of 96 integras didn't throw that code

Yours shouldn't do it anyways because it's an OBD1 car. OBD2 cars ('96-up) will throw this code when a test pipe is installed. My GSR did the same thing when I put on a test pipe. The code is caused by the second O2 sensor reading a different voltage than what is supposed to be read. Best way to fix it would be to get an O2 simulator.

 

u can wrap some tin foil around it, then put the sensor back in, and that would probably fix it, however you have to replace the foil every now and then, like 2 months. YOU ONLY HAVE 34,000 miles on a 96 teg? DAMn

 

Exactly how badly did the car sound w/the testpipe?

Interested but don't want a daily driving sounding like poop.
