91crx-jace

ok heres the deal. i have a 93 del sol with a gsr swap. i just did the swap a month ago. its been running great till a couple days ago. it started cutting out just a little bit while acelerating, kinda like a hicup here and there. then it gradually got worse to the point where my car sounded like a suburu. so i figured it needed a tune up cap / rotor / plugs / wires as im not too sure when it was done last. i bought/installed the oem spark plugs, and borrowed my friends parts off his perfectly running eg/gsr and put them on my car, wires, cap, rotor, distributer, ecu, and main relay. now it only sputters a little bit while im driving through town at all different rpms, but once i get up to a higher speed it will start sputering and hard to acelerate. its really only super bad when i hop on the freeway and do over 60. what should be my next step for diagnosis?maybe a fuel problem? its just weird because driving through town it runs almost perfect at all rpms, but as soon as i hop on the freeway it starts sputering hella bad. any input would be great, thanks.
