Ok i have a 92 jeep with around 175k miles. It starts up... but takes about 5-10 seconds of cranking up. Also when i turn the car off after running it i hear a noise coming from the gas tank, kinda sounds like it is sucking around or something like that. Another thing that has happened to me 2 times so far was when i a driving it felt like i wasn't getting anything. I put my foot on the gas and it tried to go but it would get above 30mph it just kinda sputterred.
