Hey Guys-

Im having problems with my 05 GT and its tune. I've had a tune from Brenspeed for about 3 months. My exhaust setup is stock headers, Pypes off road x, and Pypes Mid-muffler cat back system. Over the past few days, I keep getting a transmission light and DTC Code P2195 (O2 Sensor). Today, the Car was shaking when idling and sputtering as I tried to accelerate. What should I do? I've reflashed the tune 2x, and about 5 miles after each re-fash, the light comes back on. I'd appreciate any help you guys have.

Were all of your mentioned mods included in the tunes from Brenspeed? If you added or changed anything AFTER you loaded the tune you can throw a code. If not, I suspect that it's something real since you've had the tune loaded for 3 months (AND assuming it's not a garage queen and has hardly been driven since you loaded the tune).

Yea all of these mods were included when I ordered the tune. If its a legitimate problem, where should I start looking? I know that I've been able to smell the exhaust a bit more than usual, letely- could that be linked?

you should being smelling the exhaust more....the error means that a sensor is stuck lean, there for there is more fuel being added to richen it up. How many times has the code come on and have you thought that you might want to take it to the dealer to have it checked? Are the rear O2s turned off in the tune?

have you called Brent or Dave at brenspeed? that is where I would start, he is pretty dead on with helping you figure out what could be happening. something has changed in yoru car to all of the sudden cause this....sputtering and shaqking is as howartmart pointed out your car is reacting to a lean situation and richening your fuel. in essence more fuel is going in that your car is not burning...are your O2 sensors turned off? they should be in your tune...how were you driving it prior to this happening for the first time? how does it drive RIGHT after you reflash it? is is fine....snappy, hesitant? there are a few factors that can be causing this. but i would definitley call Brent first and walk through it with him...sorry to hear about your issues.....keep us update on what you find out...
