Hello, I have a 1992 Cherokee Laredo with the 4.0, and 2 wheel drive. About 5 months ago my battery would not hold a charge. So I cleaned the terminals and jumped it. Upon restart, it would not idle. If I took my foot off the gas, it would just die. I had read that the O2 sensor would start to go at about 80,000 miles, and that is just about where I was. So I replaced the O2 sensor, and everything was fine. Then yesterday during work I came out to the car and it had a dead battery. I got a jump, it started, but would not idle. I thought that maybe I got a bad O2 sensor. I removed and replaced the O2 sensor with another, but it still won't idle. Is there a common link between the battery and the fuel metering system / vacuum system or is there something else that is causing the problem. Another thing is, when I accelerate it runs fine, it's just when I take my foot off the gas that I have problems. Any help in this would be very much appreciated
