Question about 2001 Kia Rio
Hey i actually just dealt with this problem last week ona friends car. the oil in the center with the spark plugs is because you need a new valve gasket. not a cover unless its cracked just the gasket and it costs about 25 dollars at your local parts store. its very easy to install and a quick fix but try to get all the oil out of the center as you can and rub a little bit of old oil on the gasket before you install it. it helps stop dry rot. try this first and then see if the backfiring and stalling stops. if not, you may need to change your spark plugs again even if you already have because chances are the oil thats already in the hole has burned up the spark plug. so give your spark plugs a good check while you change your valve gasket.

If you have a twelve pin connector for test, (just to the right of the column under the dash)you can jump from the second terminal (going right to left) on the top row, and ground. ck eng light will flash codes.
Personally from what you have said, i'd lean towards either coil, fuel pump.or filter. See if you can pull codes...

If it is oil, the oil is leaking into the cyliinder past the piston ring. You need to have this checked by a mechanic orherwise you will have a more expensive problem.

you need to check the fuel pressure,and did you mean you replaced the distributor or just the rotor because inside the distributor is a pickup plate that some times causes this also 02 sensor can cause this.is your check engine light on if so go to chain auto parts store they usually read your codes for free.
