I have a 2001 I30 that dies at cold start if you don't give it extra gas. Car starts fine later in the day but has this problem when sits overnight. Also idles rough when at a red light after sitting for awhile. RPM seems to oscillate.
i have the same problem with my 1998 i30 im trying to figure it out now because it never ever did it before until this year pretty pissed about it lol if i hear anything i will repost to you with an update
