    Default whats wrong with my e30?

    still trying to get the new car running better so i can start using it as a dialy driver. the car is a 1989 e325im about 160K. heres the new problem. i'll describe it the best i can but i just changed my own oil for the first time about a week ago so im pretty new to working on cars.

    it has a bad idle. well it does it the whole even when running but it's slightly better when warm. the symptoms are minor engine surging while it idles. it probably goes up about 3-500 rpms and everytime it does the red engine light would flash. and it goes away right when the the engine slows back down.

    ive changed all the oil and looked at the o2 sensor checked the plugs, wires and distributor cap. made sure the oil cap and dipstick was tight. mass airflow sensor is new but its aftermarket so i dont know anything about it. hoses look good so i dont think theres a leak in the intake or anything.

    im not sure what is wrong. i tried searching for stomp test but couldnt get any info is it the same as doing it on later cars? whats a good site to get the codes decifered?
