gas problems?!?!

[txboy99]

my 99 323is suddenly is becoming increasingly inefficent with gas and it seems like its losing 30- 70 miles per tank. I have owned it year and its at about 90000miles, and i havent done any major work on it since. Is it time for a fuel filter switch out and is ther an easy way to tell?

go to pep boys or kragen and buy one of those fuel filter cleaners or oil filter cleaner it might help

I'd change your air filter and fuel filter to start.

Have you done a tune-up lately? BMW spark plugs last less than 10,000 miles. Whenever I change mine out the engine runs much better. And check the air and fuel filter. :)
