For about a month I've been ignoring the "service engine" light on my 98 Disco I with 86000mi on her, until my "check engine" light came on recently and I figured I needed to take care of some issues. So I reset the "service engine" light and drove about 10 miles into work and then the "check engine" light went out too. Is it possible that the "check engine" light came on because the "service engine" light was on so long and I have no reason to be concerned? Or should I look further into the "check engine" alert?
