Get the codes read at the parts store. Write down the trouble code number and post it here. Someone will advise the most cost effective solution. There may be pending codes that have not lit the CEL yet.

Well the codes it gave last time were -low fuel pressure -vacuum leak on engine -failed ho2s -faulty vehicle speed sensor -poor electrical connection -open or short circuit condition probable cause -air/fuel ratio -Fuel injector fault Those were the codes that were given too me while my car was running at a rough idle replaced the maf sensor cleaned the throttle body and now it doesn't even wanna start ?

well in base terms you just answered your question you only scratched the surface. engine that starts and stalls is most commonly 1.loose or faulty wiring * check this* 2.insufficient fuel reaching the fuel injectors. 3.vacuum leak. at gasket between the intake manifold/plenum and throttle body. 4. intake air leaks (broken vacum lines) 5. contaminated fuel. I have the hynes manual and im just stating the comman problems for said issues. and if you had a bad idle before try checking the crank case hoses they are most commanaly the main cause of bad idle as they get cloged over time from short distance stoping and going. a cloged fuel filter will also cause stuter
