well i was doing some normal routine maitence on my 2ngen teg and put in an o2 sensor today... im driving around after putting it and it likes to bog out between 2,500-3,000 rpm.. i just basic bolt on's irecently looked at my cat just to check it out and it seems to look fine on the inside from both sides.. my question does anyone have any ideas as what coud be going on or how to resolve this...

 

Did you reset the ECU? That might help if the other O2 was shot. Where's primerville?haha Good luck.
