Have you recently made any changes? If so, check to make sure you don't have any vacuum leaks. If not, talk to Torrie (your tuner) first.

I have not added any performance mod. The only mod i did was the engine tower strut. This was torries response "My guess is its some sort of problem with the vehicle speed sensor. It’s not common so I would imagine it’s a physical fault".

You might want to check with him again, I think he's confused or fat fingered the code. That code is for your oxygen sensor, nothing to do with the vehicle speed sensor.

Did you clear the code to see if it returns?
Your SCT tuner should be as to do it.

Not yet [MENTION=22912]Chef jpd[/MENTION] .. i know its the o2 sensor but it looks normal to me from my understanding of this CEL is that the engine is running too rich and the o2 sensor is telling the ecu to lean it out(put less fuel). Im guessing is due to the weather being colder and the tune. Correct me if im wrong.

It is very likely you're correct, that's why I recommended to talk to Torrie.

So it's the other way around, you're running too lean which could easily lead to detonation. Be careful with it until you get it fixed. The fact that you're reading lean A/F is enough you won't need to clear the code to see if it comes back, it's already a problem. You're LT fuel trims are probably pegged.

I see if i change it back to the summer tune the air to fuel ration stays around the 14 to 15 and i get no check engine light so idk it might also be calibration of the winter tune.

Maybe but remember, it takes a little bit for the fuel trims to learn. Don't just be satisfied by what you see immediately, watch it close.

I see your point. damn so much science into this tune/car things i will try to send the specs to torrie and hopefully he can help i wonder if its a part ima have to replace or a recalibrated tune.

Almost positive it's tune related.

15-16 is too high. 14.08-14.70 would be the normal range for E0-E10 gasoline. Since you flashed back to the summer tune and it appears to cure that problem, I'd definitely say it's tune related and recommend, like the others have, that you contact Torrie and let him know what's going on. Not that we mind to help, but more often than not, it's best to start talking to your tuner when something is up rather than self-diagnosing on the internet. I say that because running it lean (15-16 AFR range) could really do some damage while you're trying to figure it out and I wouldn't want to prolong coming to a solution.
