problems with my 99 mounty

[Mountaineer924]

well last night i was coming up to a stop light and at idle my car would shake..it was weird and when rolling from about 1-6mph it was worse...couldn't feel it to much after 1st gear. anyway a little later my check engine light came on so i was like ah crap..i added a quart of oil(i was low) and that calmed the engine downa little but not by much and the CEL was off. then this morning it was on..im not to sure what it could be..fuel pump? injectors? spark plugs? im 16 and i need a car for school--any help would be appriciated!!!
thanks,
Kyle
