Sputtering On Acceleration

This is my problem.. I have a 1992 Eagle Summit Wagon (1.8L 4Cyl/5 Speed).. Was running fine after a replacement computer was put in, the same thing happened to mine that happened to everyone elses, the capacitor blew.. But that's fixed.. Now I have a different problem, it was running fine for about a month, and now it sputters on acceleration, it wasn't bad at first, maybe a miss or two every once in awhile, now on-ramp highway acceleration is almost nothing, it loses power at around 4,500 RPM, I don't know where I should start, I tried changing gas stations and putting some $7 bottle of fuel system cleaner in there, that didn't help so I don't think I have water in my tank, I'm thinking it has to be something to do with the spark, I don't know where I should start tho, I already changed the spark plugs, no help there, I'm just looking for a second opinion, maybe spark plug wires or distributer? What else should I check? Fuel pressure regulator, injectors? Thanks in advance!
