hey everyone.
i have a '96 civic ex coupe--stock. i just replaced my primary O2 sensor w/ a bosch, instead of OEM. the mileage seems to be back where it needs to be, but the bosch gives me a check engine light when the car is cold.
i have tried two new bosch O2 sensors w/ the same results. i never had a check engine light w/ my old sensor--i just replaced it, b/c i was noticing the symptoms of it needing to be replaced.
i have a scanner, and the sensors are working fine. i'm getting code--P0135--'electrical problem w/ primary O2'. my old O2 sensor doesn't even do this.
like i said, it is only when the car is cold, and for the first minute of running. anyone else had problems w/ the bosch's?
i've only had my civic for a few months, so all help is greatly appreciated.
zack
