A few weeks ago, my 2000 Jeep Wrangler would not start. I would turn the key in the ignition, and it would initially try to turn over, and then just start clicking. If I tried a couple times, I could usually get it to start. I replaced the starter about two weeks ago, and it seemed to fix the problem. Until a few days later, and I was trying to start the jeep and it was clicking, instead of starting. It just happened once, and I was able to get it to start when I tried again, a minute later. It worked fine from then for about 7 days, and yesterday when leaving work, it had a problem starting again, it tried to turn over, and stalled out. I was able to get it to start but had to give it gas to keep it from stalling, as it wouldn't idle properly. I drove it through the driveway (about a 1/2 mile to the entrance), and it stalled if I had to come to a stop, at which point I would restart it. After it warmed up for about 5 minutes, it ran fine. The battery is only about 2 years old... Any ideas?
