Hello fellow BMW enthusiasts,
I am a new kid to this forum so forgive me if I dont follow correct protocol. I have a 97 328i with 177k mi. In june my check engine light came on and took it to get analyzed. anyway I replaced 2 precat o2 sendors, air mass sensor, rubber boot after AMFS, seconday air pump, and diverter valve. The check engine light is still on and now the engine runs rough and the code reads a rich mixture. I am now in the process of taking off the manifold, replacing gaskets/seals, and checking for any vacuum leaks.
Anyone out they know what else could be causing my engine to run too rich?
Thanks, Bob
