on my way home from school today the car ran perfect. When i got home i left the car in the driveway idling for 5 minutes and the when i came out of the house the car kinda sounded like it was stumbling or like it was misfiring. I tried to drive up the hill and it barley ran. I checked for vaccum lines but everything was good, checked the coils those were fine and there no check engine light. Im Not to sure what it is, it happened out of no where. I cleaned the MAF sensor and the IAT sensor but no change. Im gonna change the fuel filter and see what happens. If anyone else could help out that would be cool, Thanks guys.
