Hi guys My 2007 BF XR6 Turbo sedan is running rough ever since removing the battery to replace a drivers side light bulb (headlight). And also it has brought on the traction control light on dash, but when I go to turn it off it won't turn off.

It was idling rough and felt like surges.It also stalled once. Drives fine on motorway but once changing down gears and putting into neutral it starts to surge and slowly corrects itself.

Then why right it twice :stirthepot:

 

Its the tapatalk app.... turn your signature off and it will stop.

 

As for your actual issue, is the car tuned at all? do u have a xcal? if so reload your file and it mite clear the problem itself.

I originally took my car into Jack beedham's to get a sensor looked at it was the catalyst efficiency below threshold bank 1 code coming up so they took the twins Catalyst converter off

 

And replace it with the standard catalytic converter however ever since putting on the new catalytic converter it has produced a new code po1 33 O2 sensor slow response

O2 sensors are not supposed to last the life of the vehicle. Off to repco or whoever & grab a decent one (I prefer NTK ) -just make sure you get a 'direct fit' which comes with the right connector.  Contaminated fuel, coolant, even using the wrong silastic can contaminate them. they relatively cheap & it cant hurt to have anew one in. I would only change the frount one (sensor 1 ). its fairly easy to change & you need 22mm spanner
