Alright, had the jeep sitting in the yard all summer, maybe about 4 months now, i fired it up maybe once every week or every other week, and it eventually wouldnt turn over (dead battery), so i put a battery tender on it and it would fire up but slowly, when it did, if i let off the gas to try and let it idle, it would die shortly after. So anyways, i assumed after searching this problem here that it was just a bad battery. I just bought an optima red top and it no longer needs the battery tender obviously, but for some reason it didnt fix my stall problem...initially it did...i let it warm up and didnt have to keep the throttle up....so i thought i was set...but after driving it around for maybe 5 minutes...i was back to the same problem. What should the next step be, TPS maybe? Any ideas much appreciated.
