Hi everyone. So i have a 2011 mustang gt with 66,000 miles on it. The car has no cats, a borla exhaust with and x pipe and a bama tune. The car wont pass emissions here in Illinois because it is saying the heated o2 sensors are 'not ready'. The lady who tested the car at emissions asked if the car was stored alot and that could be a reason it failed. The car is driven pretty much everyday but she said if you are just driving it 30-45 with stopping and turning, how my car is driven, that isnt giving enough time for it to heat up. The cars o2 sensors were tested and they both are running good and not sending any check engine lights to the computer. The cars exhaust since ive bought it in july has always smelled like straight fuel. So now what were thinking is maybe the tune is messing it up? Is it worth it to retune the car myself? Or bring it somewhere to put a better tune on it? Ive heard about o2 simulators will that work? Or does it just need to be driven on he high way to really heat up? Or just go back to all stock for a day? Dont want to give the car up so willing to do anything.
