skidisk

Hi. I've search the threads and it seems I should first tighten my gas cap, drive a couple of days and see if the CEL goes off. So I'll do that. But I also see that MY2002 has an egg shaped fuel filler neck and that causes problems. Is that also a problem for MY2000? Is there anything else I should be aware of? I have no other symptoms; the car runs fine and I've not done any mods to the car and it is stock (except I just replaced the rims with 17" and new tires last week, which seems irrelevant).
