hey guys, so i've had my cherokee for quite a while, just havn't gotten into the forums till my car came along. Anyways, today i was out wheeling with a friend and as usual my jeep gets hotter while revving a lot and not going very fast. so as i was waiting for someone i shut it off for a bit. when i started it back up she was running kinda rough but then cleared up. then a while later i noticed the check engine light was on. it never has before so i'm kinda weirded out. i've got a 97 cherokee sport... straight six. yeah, new here so don't know what your all dealing with, but anyways word of wisdom would be awesome. i'll prolly look into it more tomorrow but ideas would be great. hope this forum is as good as my cars.

Welcome to CF Landon. Since the CEL came on check and see if there are any codes set/stored.

Landon

thanks man. so just check it out at an auto parts place that reads the codes? thats what i was figuring on doing. i'll let you'll know whats up. thanks for the advice!

vapor lock. these 4.0's run real hot, so when your out on the trail either leave it running or open your hood to let it cool a little. it's happened to me a few times and i've seen it happen to other XJ's on the trail. get the codes read and i'm pretty sure it will read as a cylinder misfire.

Landon

yup. cylinder 2 misfire. no problems now. lights off and doesn't turn back on. thanks guys!

I found this: http://jeephorizons.com/tech/xj_cooling.html . I don't know if it applies here but it sounds like it could be helpful since a lot of 4.0 owners are having overheating issues.

Happened to me this weekend...but it was a misfire as well...
