so i seem to be getting a p1133code here and there every so often and i have already tuned the rear 02s out after my header install. any ideas how i can solve this..its alil annoying now that its cold out and i cant use my remote start to warm my truck up when the check engine light is on..lol

from the lil reading ive done this could be caused from the wrong location of the front 02s so i would have to put new bungs in.. in whatever the right location is?? and it cant be tuned out as its not a software issue, if i turn them off it with make a fuel issue...anyone ????

My tuner said they can be turned off. I have the same issue. Mine started two days after the tune but I had a very loose passenger front sensor. So I tightened it. Then it came on again. Checked all my connections and reconnected them. Of course with negative terminal disconnected. It would reset the computer and make it go away. So I called the tuner and he said they could be turned off. Some vehicles need this for some reason. Now, Im not a tuner but, how I understood it was whenever I punched it, the air fuel was too drastic, it would throw the code. It doesnt affect the performance on mine just annoying. It doesnt idle rough or shitty. It hasnt come back on thou since I checked the connections last and the sensors themselves. I deleted the codes with scanner too. So that might have helped too.
