1985 ford ltd crown victoria 5.0
 

Car was running great then all of a sudden can start it. Once in a while I can but cant keep it running. Idle goes up and down then dies. If I get it going it stays running only after I give gas at the right time to pass the low idle and after I get passed that only stays running if I'm at 3/4 pedal. Any less and dies. Cant put in gear. One thing I noticed is injectors sound much different than before. More like spitting than even spray. Cant figure out how to take off or find online the ones I have.
