Who out there is gettin crappy gas mileage and can't stand it? This kid. My 02 Grand Prix sucked down the gas like you wouldn't believe. Gas going up + crappy mpg = SUCKS!!! My stepdad has a 96' Impala SS. He replaced his stock Mass Air Flow (MAF) with a more input one for his car. Since he didn't need it I put on my Grand Prix. Replaced the air filter, and BOOM!! My mpg went up at least 6-7 mpg.. I couldn't believe it. Want better mpg. Give that car some more air.
