Hey guys, I've had this problem for a month or two now. After leaving my jeep parked overnight or for an extended period of time 8 hours or so, after starting it up it runs very rough for about 2 minutes and then it smooths out and runs fine. I've replaced my upstream o2 sensor and cleaned my IAC and that didn't help it. Anyways I uploaded a video to youtube where you can actually hear my problem.
please take the time to watch just the first 30 seconds to hear my problem and let me know what you think it could be. I have a 1997 Jeep wrangler TJ with an automatic transmission. Any help is greatly
