My NSX is sputtering under anything but WOT, so I'm thinking it may be the fuel filter. I just got the car three days ago and I can't find out where the damn thing is. I also ran lucas fuel treatment which isn't working. Please help!!
I get a CEL with the Orange TCS light together. I have no idea if that has anything to do with it. I guess I should start with filter, plugs, etc...

True...But the verdict is the O2 sensor. Disconnected it and it still runs the same and it threw the CEL. Thanks to all for the help!!!!
I believe the point was that you disconnect the O2 sensors and if it then runs "fine" it is the sensor. If it still runs poorly, it is not the O2 sensors.
Check the stored codes.

First - Listen to Brian and Larry. They know what they are talking about.
Second - If you disconnect the O2 sensors and the car runs OK then the
sensors are bad.
Third - If the car runs OK at WOT then it's not the fuel filter. However it
could be your fuel pump. This car has a 2 stage pump. To test it
you need to strap out the fuel pump resistor which forces the
pump to run at max pressure all the time (the resistor is located
just above the fuel filter and it sounds like it could solve your
problem). If strapping the resistor works then your fuel pump is
bad.

i dont understand your logic, when you say "strapping out do you mean jumpimg out the res., yes tthis will cause the fuel pump to see full voltage, (nsx uses a two stage control for the fuel pump not a two stage pump)(but he said the car runs fine at full throttle ,his car is experiencing a rough idle & throttle tip in sputtering , most likley a vacuum loss , put a vac. gauge on at idle (my car ,97 pulls 21 ") Idont like to diagnois problems with out seeing the car ,this just doesnt sound right ,he could have an EGR problem or some thing along those lines
