I need help trying to figure out what is going on with my car. I replaced the O2 sensor about 6 months ago. The guy at the testing place said that my car was running too rich. I have also adjusted the timing. I can't seem to find anyone else to help me. I hope that someone can. It's a 1994 Honda Civic Si hatchback with the D16Z6. All stock.
