The car will turn over but it wont keep running, it dies after you let go of ignition. Before it did this it had idling problems ( too low ) and would sometimes die. When it finally died on me it went about 15 mph and then reved to higher rpm's and choked out but wouldn't go nowhere. I got it to start again after that but it went like 100 feet, died, and would not start no longer. I already replaced the idle air valve, throttle positioning sensor, and the alternator. There is no vaccum leaks and all fuel and oil pressure is optimum. What could be my problem? I thought maybe o2 sensor or distributor sensor if your advice works I sincerely will donate i'm sorry ican't afford to pay anymore money for help that doesn't work i've done enough of that

The MAP SENSOR could be a possibility but don't take my word for it. Ask around for other opinions about this possibilty. It cost about $50.
There are so many sensors on these things and I spent a small fortune trading out parts trying to figure the problem on my 89 Cherokee. It turned
out to be a 50 cent piece of hose on the fuel pump!
Where are you located? Could be a possibility that I could loan you some of the parts I have, to help you find your problem. I would have to know a little more about ya just so I can trust that you would return them once you are through. I realize this may sound a little to trusting and maybe foolish on my part, but I have been there and I know the expense and frustration. I am a lower income dad with 5 kids and could not afford to take my Jeep to a garage but at the same time, I couldn't afford what I spent on parts either. But, I had to have a way to get to work. Anyway, you can respond on this site or email me at samuelje93@yahoo. Com
