Hrmm...CEL came on
I went off-roading...in heavy mud, over the weekend. During my lunch break the CEL (check engine light) came on. What all could trigger it? On a Jeep is it like the rest of the OBD2 vehicles out there, where the CEL is mainly triggered by emission related problems? I've got the factory repair manual @ the house, I'll run the codes when I get home. Just looking for any info up front!
