Having a bit of an idle issue and could use some input. My 93 civic lx has been idling very low as of late (just above the 0 line) and occasionally dies. It will start right back up with no problems every time its happened. Its been happening more often lately as well. I noticed this last week that when i first start it up in the morning it idles at over the 1 line but drops super low again once its been running a little bit. Its an automatic trans. What could be causing this problem and how can i fix it. Ive been searching but cant find an answer to the same problem as mine, i will continue to search on here as well. Thanks for any help.

edit: also the idle does not jump around at all, it idles very low just about all the time. sometimes it idles normal but mostly very low.
