Default Rough Idle and bad acceleration

Hey guys first time on here. I have a 1994 Bonneville 187,000 miles that all of the sudden a couple of days ago started to idle really rough, i then started to accelerate and it hesitated a bit and the once i got up to 40 mph (very roughly) it was like my car had hit a wall. so to continue accelerating i had to almost put my pedal to the floor. If i start up really slow i don't really have an issue but it still is idling pretty rough. I did some research and saw that people suggested replacing the the spark plugs and wires and i have also heard fuel filter. I love this car and want to to keep going. Any suggestions would be appreciated. Thanks!
