check engine light on, on 95 s14

[GReddySTi05]

So i had a check engine light on, i checked it a month ago and had 3 codes, 32-EGR Malfunction
33-Front 02 Sensor
125-Line Pressure S/V

and i got rid of the codes, then i check it today and all it says is
55-Normal engine management system operation is indicated – this means all is OK.

so does this mean its all good? because the light still stays on, and i do think it needs a 02 sensor

if it stays off your good. not to hard

nice it stayed off, sweeeeeeeeeeeeet, oh i also think i know what happened, i started using only shell 91 octane for over a month and a half, i think that fixed the problems, i just bought this car 2 months ago so just trying to fix it up, dont think previous owner used 91
