I just purchased this 2007 GT and it will not pass marta because of the following issues:

Catalyst-not ready
Oxygen Sensor-not ready
Oxygen Sensor Heater-not ready

The car has a Ford Racing CAI, Pypes LT, High flow cats, Ford Racing axle back exhaust. It runs great so I am assuming someone has tuned the vehicle. Any way to change the tune so I can get it through TN emissions? Any help would be greatly appreciated...Thanks.

So in the tune they turned the rear 02's off. I don't know how strict your state's tests are. But if they are just hooking up and reading your 02's are turned off, it is in the tune. plus I would assume it's tuned with the cai and lt's. Since going back to stock isn't an option, I'm not sure if there is a safe tune you could run with this setup just for thie emissions test?

Thats Sucks. I hope I can figure something out. I don't know what kind of tuner was used. TN does the computer testing. I think I could pass a sniff test pretty easily.

brad281

It does. I would also be careful and make sure the ford dealership doesn't flash that car back to stock while you are running those mods and that custom tune. Previous owner should have at leat left the handheld tuner that's locked on to that vin and mods.

if you don't have a tuner, your going to need one, buy one from a comp. that will write you a smog tune, also buy a couple of O2 sensor spacers and put them on the rear O2 sensors, this will help the sensor get a reading with the high flow cats,

jcook24

By spacers do you mean extenders or something that extends the sensor out of the exhaust pipes? It has extenders installed all ready. Thank You for your information.
