OK, I have a question about O2 sims. i just had 3in piping run from the manifolds back with 2 sweet thunder mufflers dumped installed on my car. i kept my from O2 sensors but removed the rear O2 sensors. and i seem to be getting not as good gas mileage and i have an SES light. so if i got O2 sims would it help or are they even necessary? or can i just go to the dealership and have them delete the code and my car will run fine? it seems kinda sluggish down low until it gets above 3500 rpm.

you could definitely be having an issue if you havent had the car tuned for no rear 02's. It will make the car think that the cats are functioning improperly and mess up you a/f and possible put the car in limp mode, thus making it sluggish. If you interested in some used 02 simms i have a set for sale in the classifieds section. Good luck

Thats the link to my sale. In regards to if it will cure your problem, i'd reset your pcm and put the 02's in, you shouldn't have any codes and it should run better. You probably wont run at 100% because the car will need tuning for the a/f to be perfect and to make the best power
