Was the low fuel light on or ABS or T/C?

I saw that the car was low on gas too. Fill it up then see if it does the same.

I would also take the car to the parts store and see if there are any codes that are being stored but are not showing up in the CPU yet.

Is it tuned, chipped or have any parts just installed recently?

Thanks for the respone, the light is abs, the problem is there even if I have low fuel or full tank, there are no soft codes in the ecu, and i just tuned it with sniper, but the problem was there before and after... everything else is stock.

thanks, maybe, but that would trip the CE on because the rear sensors should read a different afr??.. and why the problem is not present when the engine is cold...
