Check the gasket on the gas cap if it's in good shape try tightening the cap firmly.

1999 kia sephia loses power when gets below 3/4

Check for a restriction in the fuel tank breather. Also, try taking off the gas cap when this happens. If taking off the cap fixes the problem, you need to see what is stopping the fuel tank from breathing.

I own a 2001 Sephia LS..."The O.D. off" flashing with "check engine light" didn't have a thing to do with an engine was simply a bad connection in one of the 3 plugs that plug into the back of the instrument cluster!! I removed the cluster, pulled the 3 plugs, cleaned them and put it all back together...No problems since. By the way...mine has 112,000 miles on it

Check engine light on and O/D OFF light flashing

I was facing a similar problem when I bought my car, I think the "check engine" lit due to a problem with shifting control system which obviously made the "O/D-off" flashes.The best solution in this case is to replace the malfunctioning shifting control system (a closed steel box that works like a computer).This is what I did and since then it's running perfectly.
