Malfunction Indicator Light on

[cpewI30]

I have a 1996 I30. Yesterday the Malfunction Indicator Light came on. According to the Owner's Manual, this could mean a problem with the fuel emission. What would this entail? How serious is this? How expensive to fix? My other question is whether this has anything to do with a problem I was having with the car a few weeks ago, in which it would idle roughly and then die when I stopped at an intersection. It would start right away, but then die again whenever I came to a complete stop. According to the mechanic, it was an idle control valve problem. It's been fixed, and it hasn't stalled since. But are these two issues related?

Thanks!

You have OBD II, why not scan it for a code?
