It's been a long while since I posted anything on here. I visit often for help and advice. I need some help now. Recently my Jeep died on the way home from work, it sputtered a little and then died. Would not start. I had fuel and what I thought was good spark. Turned out that the spark was weak after reading that was a possibility. Changed the coil and it started right up. The issue that I am having now is it will start right up when I barely turn the key and if I let it run for a minute and then shut it off it won't start again unless I give it gas. If I drive it for a while and shut it off it while start fine. I have already taken the throttle body off and cleaned it up as well as removed IAC and cleaned it too. It was acting the same way after that so I replaced the TPS and it still doing the same thing. I was having this problem some already before it died on me when the coil crapped out. Any advice on what to do next would be appreciated. I bought this Jeep new in 97 and although I have newer vehicles to drive I still drive this to work everyday. It has 298,000 miles and still runs like new.
