i got a civic ex sohc d16y8 and my check engine light is on cuz of my c o2 sensor .when i start the car (cold start) the check light starts to flash and all of my lights like my headlight n breaklight but not bad just a little you got too focus on them to see it. when the car warms up it does it but just the check light alone and not as bad. sometimes when i am driving it struggles through the rpm's just from 0 to3 or 4rpm and my (srs) light comes on but not all the time what can this be?
