Poor fuel economy and code p0157

Hi lets start by saying a few months ago i took my car and had the emmisions tuned out. well it seems ever since then my fuel economy has been horrible. also driving the other day i got code p0157? which is for rear o2 sensor which i thought i paid to be turned off. can i still get this code if my emmisions have been turned off. let me know what you guys think.

thanks

I'd suggest a scan/data log be done, to see what's happening. Sounds to me as tho the "tuner" has gotten some "issues" tuned into the system...

should i take it back to the original guy or should i take it to a third party and have them look at it. I guess my main concern is why i am getting a code for a rear o2 sensor when i paid him to tune them out. i guess i should just go out and unplug them and see if any codes come on. am i correct or will i still get codes for rear o2 if i asked him to tune them out?

thanks

well i did some digging and asked alot of people around here and even called another shop and they said that i shouldnt have gotten that code if he turned off my rear o2 sensors. guess i need to call and confront him. i hate doin that, im not very confrontational. oh well
