    Check Engine Light Help

    Hey guys. It's been awhile. My 1988 ix has been great to me so far. I am having an issue that I am hoping someone might have an answer for.

    I recently started having my check engine light come on. Now, I own a 1988 which has the 1.1 montronic. Which means there are 4 codes. The code that it is setting off is two flashes, which is the oxygen sensor malfunctioning.

    The weird thing is that I have recently replaced the o2 sensor with one from bavauto. The check engine light comes on during acceleration, usually second or third gear. After a few days, it turns off, and then inevitably turns back on again after accelerating from a stop light.

    I have a k&n drop in filter, would that be causing the sensor to malfunction? Is there something else I am missing?

    If anyone has any ideas of what is going on, or where to start, I would be very appreciative. Thanks in advance.

      Alright. Thanks nando. I'll probably just replace that and see if that helps.
