Our 01 rio is throwing code 1166 and 0130 but we just put both o2 sensors on it. it seems to just all of a sudden start to sputter and lose power. when we turn the air on it gets even worse. we had the catalytic converter checked and its ok. also when it does lose power and sputter if you push the gas pedal to the floor it comes out oof it or if you work the pedal a little it sometimes comes out of it.

There is a black rubber button reset switch right next to the air box, press it sounds like the problem i had its a fuel pump reset (just in case of a wreck it kills the car) but there is a tiny ball in there and if it is rattled a little too much it will fall and you need to press the black looking button to reset it....took me like 4 months to figure it out

try your crank shaft sensor, sounds like the same problem i had , had crank shaft sensor replaced and it drove fine afterwards. maybe go to auto zone or something and see if that code comes up
