ok i got the sensor replaced, and got the codes cleared. I had a code P1131 which is why i replaced the sensor in the first place, but every now and then the car will almost buck. like it's misfiring (but it isn't)and it will accelerate sluggishly. The CEL will flash, but not stay on. this does not happen everytime.
Has anyone else had this problem? could it be the O2 in back 2 that is causing this?
