hesitation in throttle response

[TmaCular]

i have a 94 q45a recently converted suspension over due to fried pumps and accumulators.. everything on it works perfect and it runs beautiful. but i notice in lower rpms accelerating is hesistant possible fuel filter?? i just got home from a 1500 mile round trip to ny and it ran great at high speeds and cruisin so i would not think a fuel pump or relay issue considering fuel pressure must be ok but i also do not know much about these cars any ideas to check out?? thank you in advance for ur help

fuel filter, throttle cable, dirty injectors, air filter, maf \i would change the filtersrun a tank of gas w/ BG44 or Techtron.change air filter clean Mass Air Flow SensorCheck tension on throttle cable

A common cause of hesitation are the infamous knock sensors which will cause ignition to retard. A quick ohm check will normally tell you the story. Another positibility is the TPS.
