Poor performance after header install

Just installed long tube headers on my 93 z28. Now the car has a bit of a rough, luggy idle and acceleration. I blocked off the egr tubes, do I just need to get the egr tuned out now? I am also pulling code #13, which I believe is an o2 sensor issue.

The poor performance is most likely due to your o2 sensor(s).
Code 13 - Bank 1 (left) Oxygen Sensor (O2S) Circuit (open circuit).
I would check the wiring to that sensor. You might need a new sensor as well.
Also check your wires to see that you have all the wires onthe correct plug and none are burning up against the headers.

an o2 sensor will actually read lean from a dead cylinder, they do not measure fuel, just o2.
But i agree, check plug wires for damage and (i have done it) being on the wrong plug. Also did you get o2 extensions or did you make your own?

Made my own wiring extensions from the old sensors. The headers are not coated.
I'll take a look and see if I can find any connection problem.
Edit: Although I don't think I made an extension for the left sensor.

My car is kind of popping, almost sounds like a slight backfire on a cold start...is this another symptom of a bad o2?
And where I can find some single wire extensions for a 93z?
