Check engine light on 96 cobra??

I've got almost the same problem, but haven't paid much attention to the miles. Every once in a while it will come on. Some times hot, sometimes cold etc. No real pattern. Also read something in owners manual about running low on gas, but not out, and air bubble gets in there and doesn't get out even when u fill tank up. So i've been trying to fill my tank when it gets half full to see if it helps.
