My 2008 mustang gt o2 sensors and evap will not go ready for the NJ emissions test!.I tried to go thru the state inspection and it failed to pass just after I registered it.The next day my smart /SJB went bad and taken care of from a local Ford dealer it probably was from the heavy rains that we had and very costly from an earlier thread that I got some responses from!.That part is fixed but the car has Flowserve exhaust and headers.The previous owner had past it in maryland state emissions but I have tried everything that I had heard of from blocking off the one side of the exhaust and driving over 80 miles to switching to other side of the exhaust and driving several more miles with a 3 inch width pvc pipe and running premium fuel 93 octane and blocking most of the air filter high flow with saren wrap another person said they try it with there 2008 gt and took care of it!.The battery idle no start 12.7 volt running 13.4 volts seems pretty good as could be an issue by other people but I don't think it is it?.Do I have to take to custom tune speed shop to get rectified.I checked it with my scan tool the 02 sensors pass but still not ready in the car's computer.Any answers.
