I reciently bought a 99 s-10, it ran great! I was getting about 15mpg driving like I stole it. But about month ago I noticed that it started to sputtered when I started to accelerate past 15mph. I also started to notice that the gas milage started to drop. so I started driving like a granny. Now it sputters all the time and shifts hard, the gas milage dropped to 11 and I am starting to loose power. The service engine soon light came on but stays on for a week or so then turns off. i checked for leaaks and found none. Is it the fuel Pump or something worse?
