    servise engine soon

    ok i do have a problem with this. when i read the problems it is sayin 02 sensor low voltage... well i changed all 02 sensors and spark plugs and wires. and i still getting this.
    it is only comes up when i increase speed very quick and after that it is stays . if i keep push the car over 160kmh it is start blinking. after a while when i drive below 50 kmh like 6-7 km sign goes away. do anyone has any idea why that is happening and how to fix it. only think that i am assuming could be problem is catalytic converter but i am not sure. please let me know why is that and what do i have to do to fix that.
    thank you
