Hi guys, i was wondering if anyone knows about this Code p0170

My afrs just jump from rich to very lean, got very bad idle, when i floor it the boost kicks in and rpm cuts off at 4k, sounds like a misfire. when i rev the car at neutral it cuts off around 6.6k

I guess its the O2 sensor, the last thing i did with the car with the Innovate LC-1 Simulation with Link v3, Must have sort the 02.

I have also uploaded a few videos of the issue to my dropbox.

Would appriciate if anyone could give me an input on this.

Thanks

P0170 is usually caused by O2 sensor but it can also be due to volume air flow sensor, injector, fuel pressure, intake air leaks, ECT sensor, intake air temp sensor, barometric pressure sensor, exhaust manifold cracks, incorrect fuel used, ECU failure.
 
@luv2rallye I was unable to find our the issue, i am now getting a p0170 and p0110 CEL, i dont know where to start and my car has just been sitting, could you have a look at my logs if you know anything about link ?

Because my o2 sensor reads well, mar is fine, fuel pressure reads fine, ect sensor reads fine, i have tried to drain out the fuel and its the same.
