Ok so this has been on going problem the car will be dead in the morning or when driving i will start to lose instrument cluster. I have replaced alternator and replaced a bad looking battery cable. Now i have also had my check engine light on for about 3 months now before you say idiot i know exactly what it is and check it often its the first O2 sensor heres the thing i have replaced it TWICE!!! still getting check engine now im starting to think its all electrical related. Im at a total loss could it be shorting? or is it the ECU? or what i have no ideas anything at this point would be helpful.
