I just went to autozone and all that comes up is the o2's. All four o2's are throwing codes. I bought MIL's for the rear ones but they ended up not working, and the fronts are throwing a delayed signal due to the LT's and the o2 sensor being further away. The guy at autozone said that my car was bucking cause of the sensor problems, and he went on to say that it was hurting my car and what not. Pretty much didn't believe anything he said lol. But I'm still puzzled on what it could be no other codes then the 4 o2's. I still think it's a fuel system problem. The car bucks at a steady speed between 40-50mph or when cruising at low rpm's. Any ideas now? I'll check the sticky i didn't see it. Thanks

 

Also I'd like to say that i was planning on ordering gears and a tuner tomorrow but now i'm putting this on hold. But if by some chance this problem was being caused due to the o2's throwing codes will a tuner fix this? I know you can turn the rear o2's off, but what about the front. I'm hoping that the tuner would take care of all four but i don't know. I know i've herd of people throwing codes with the front o2's due to the LT's, but what do you do to get rid of that code?

 

Buy a tuner, and get a dyno tune.

 

So you think a tuner will solve my problems?
