    After installing my home made intake on my 90 prelude 2.0 si, i got a check engine light on the freeway. I pulled the code, which was 1, for the oxygen sensor. Could there be a problem such that my car is not burning air'fuel mixture completley now... or is it just a bum sensor?

    My car idles really really rough now. and i seem to be getting terrible mpt millage

    aight thanx for listening

    Rough idle and bad gas mileage are both signs of bad O2 sensors.

    Peace*

    What about resetting your ECU after your intake install? If you dont do that, dont you risk having the engine run rich?

    did you reinstall the little hose that goes from the intake tube itself? If you didn't (ie you just have a tube to the IM, with nothing else) , you need to.

    you know, I actually have not a fuckin clue what the breather does, but I'd hook it up anyways. I'd yahoo that question. Looks like that 02 sensor might be the answer.
