Hi Im new to the forum looking for a little helpfull advice for my 05 jetta tdi 5 speed. I bought the car new in December of 2004 and was getting appox 38-40 miles per gal city and 47-51 highway. Sometime in May I noticed that my fuel economy changed to 26-29 city and 36-40 highway and no modifications were done to the car. The dealers will not help me since ive eleminated my muffler and cat sometime late last month (witch did give me about 2-3 more miles per gal). I think it might me a bad mass air flow but I thought Id get some more opinions before I go ahead and order <font color="black"> </font> a new one. Thanks for your advice.
