99 Grand am 19 miles per gallon
I have a 99 Pontiac Grand Am SE 2.4 and just recently it's been getting about 19 miles per gallon HIGHWAY! I'm used to getting 25 to 30 depending on how i drive. When i start the car it starts sorta rough but other then that there really isn't anything wrong w/ it that i know of. So any help would be great thank you.

Welcome to AF stepf22 !!
Thats horrible gas mileage! If you have close to or over 100k miles, replace your O2 sensors, that should greatly improve mpg as would a tune up if it hasnt has one recently.
