HELP Engine Codes po1133

My car has been running really bad when i first go to start it in the morning. It idles high and the pipes seem to bounce and back fire. I got the car scanned with a programer and it showed the code po1133 and i know its a o2 sensor but it didnt say which sensor just said bank 1 . I changed the sensor closest the the manifold and it didnt seem to help!! The car only does this when it first starts up. seems to go away after its warmed up. it always has its moments when it acts like it has no power a spits around.. Really would like to know what to do.. Just need some help.. Thanks

you mean PO133 right? thats bank 1 sensor 1. Driver's side closest to the manifold (before the cat). is this the side you replaced? Do you have long tube headers? Did you put a new sensor in? You can always swap the sensors and see if the code follows to the other side. that will tell you is the sensor. If it stays on the same code then is something else.

Okay it just said po1133 .. which it did say bank 1 sensor 1 .. i wasnt forsure on which sensor it was but yess i did change the one on the manifold. it still seems to have that rough idle at first.
