    My first gen has a rough idle. A fluctuation in the rpm but it’s not dying. Just running like crap. The first time this happend I cleaned the throttle body and it stoped. This time I replaced front o2 sensors, mass air flow sensor and cleaned throttle body and it still is running the same. I could not get the downstream 02 sensors out. Really rusted in there! Not sure what else could be causing the rough idle. Any help on diagnosis would be greatly appreciated. My wife is about to make me sell my baby.

    Thanks.
