Bad gas millage
2005 Chevy classic, 2.2 same as the older Malibu. 80k miles. Been having a gas mileage problem, I used to get 24 city/30+ highway. Now I do mostly city driving and I am only getting 15.4 MPG. The car is very well maintained, I have never had a check engine light, oil has been changed every 3 to 4k miles. The spark plugs were changed at 60 K miles. The transmission fluid was just changed last month and I just bought brand-new tires, tire pressure has always been kept at around 32 pounds. The only thing I could think that might be causing this would be a clogged fuel filter, any other ideas would really help. Thanks
