0170 Fuel Trim Malfunction?

[2g96GSX]

I have DSM Link and my check engine light is on
0170 fuel trim malfunction, what does this mean?
At first the light would come on, but by the time I got the labtop hooked up it would go off. Now it's stays on.
What do I need to do?

I have that same problem. I have been driving on it for months but I ordering parts to counter-act it. Me and all my supra and DSM friends think it is the front O2 sensor. Also clean your airfilter. But I would suggest you change O2 sensor even though it is expensive.

my o2 sensor is not but 3 months old, but I have ran race gas in it a few times.
The car doesn't idle well eather.
