Engine runs very rough in morning.
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. YouTube - Rough start jeep
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
