Figures out codes. Anyone know which of these could be the liely culprit 11, 14, 21, 23, 24

Rpms also hunt. Generally Half way between 0 and 100 rpms. Fluctuates And feels rough

I have a 92 loyale wagon. Bought it recently figuring out its quirks. Sometimes when starting It idles very low and stalls. Have to feather the gas for a bit. Other times it idles at about 2200rpm and thenbogs down and stalls quickly. During this time engine light comes on. I have tried to figure out how to read the codes but can't find very clear information
