lt1 problem!!!

i have a 94 lt1 thats been in my daily driver for years now. ive been noticing a lack of power and kinda surging when getting into the pedal . today it just started to have a really delayed throttle response and if you 3\4 gas it from idle in park it backfires alittle bit.and like i said a very noticable hesitation when revving it up. almost like if the timing was retarded. it idles fine and drives fine but when playing with the gas or revving it up its definitely sickly. please help..anybody.. is this a possible opti prob?

Check your fuel pressure. Could be a faulty fuel pressure regulator. Happened to me this summer. Just a thought.
