1993 Mazda 323 Mileage: 170,000. The car is running really rich, especially when I start it in the morning. When the car is warm, it seems to run fine most of the time. Parts I have replaced recently are the O2 sensor, timing belt, distributor cap, spark plug wires/plugs, and air filter. I am currently getting about 12 miles to the gallon.

We suspect that the timing belt has been incorrectly installed. Double check the timing marks on the pulleys. We think you will find it is off one tooth.
