o2 sensor

[diabeticon]

Ok so i replaced my o2 sensor last week bc my cars idle was jumping and i was getting bad millage. I was on my way to work today and it started running wierd as if i fried my o2 sensor ...now im pretty sure ny manifolds are warped so would that make my brand new sensor go out.

Explain to me how you came to this conclusion? What you say makes no sense.

Nm i think its just a EGR vacuum problem not my o2 sensor.My car started running rough after it had warmed up and the egr only work after warm up so yea.

I thought it was the o2 sensor bc my exhaust manifolds are warped so it get real hot in the area and i though i burned out my o2. They basicly have the same symptoms when not working properly.
