If its clogged your car may not be getting good fuel pressure, this will cause the car to run lean. If you are indeed running rich your fuel pressure may be higher than normal. I suggest that you check the pressure.

a bad maf would make you run rich also a bad o2 sensor or bad timing

Check your air filter, too. The computer will prevent a clogged air filter from creating a rich fuel condition, but performance will be restricted.

Run a vagcom and pull the codes.

Could be anything from bad oxygen sensor, leaky fuel injectors, MAF, fouled plugs, very dirty air filter, etc.

How do you know you are running rich?

bump,

rich condition should generate codes. Why do you think its running rich? What codes are you getting?
