After I got the X3 installed I keep throwing P1133 and 1153 codes. I have changed out the 02s and that hasnt fixed after some research Ive done on here it seems like alot of people have this problem. Im wondering what would happen if I put 02 sims for all 4 02s. Would that hurt anything.. Or even work? If anyone has any insight on this please let me know ...

You don't want to put O2 sims on the front, they are used by the pcm for fueling purposes, you might cause yourself some major problems if you did that.

Cool thanks..I thought it might be a bad idea thats why I asked first

My guess would be an exhaust leak before or with in an inch of the front o2 sensors or it could be to much fuel has fouled them.

I think its probably gona be to much fuel or that they arent heating up quick enough so i may try the Vet rear 02 sensors.. I know thats fixed the problem for some guys

i run the long wire vet sensor but i dont think that will fix a heater problem. the sensors them self are the same... ac model they just have a longer wire

now the Bosch #13111 might help you out... thats what i'm running in my car about $70 each

Yep, 13111's and codes went away. My tuner says the switching looks good, no need to modify it from stock even.

The Bosch 13111 fixed my codes also.

I got the same bosch's as you guys and still get the codes. Think one of you can send me your hptuners logfile? I want to see what your switching looks like. My email is timothyberlinski@yahoo.com thanks guys.
