Car dies when I let off gas
My 99 cherokee sport died when I let off the gas. When I went to start it I had to give gas to even get it started. When I did start it as soon as I let off the gas it died. I checked underneath and no leaks or the smell of gas. So, I started it and gave it a little gas just enough to keep it from dying and put in real quick into drive. Drove around the parking lot just fine. When I stopped it didn't die ran fine. Pulled back into a spot turned it off and back on and it started right up. Drove it home. I'm going to let it sit for a couple hours and try to start it. Can anyone explain to me what happed and if I need to replace anything.
