Thread: p0134 and misfiring on acceleration

Hey all, just got done putting in my headers yesterday afternoon, took the time to fix all the little exhaust leaks before taking it for a test drive. And when i finally ran the car it threw that code and started "missing" under any hard acceleration.

I'm gonna ohm through the wires today and make sure i didn't scorch any.

P0134 HO2S Circuit Insufficient Activity Sensor 1: Check for pinched/burnt wires. What did you use to Extend the wires for the 02? Id tend to think that's where the problem is.
