Hey guys, my 2.3L 93 LX is having some driveability problems. When the car is warming up, at part throttle it stumbles and backfires, but if i put the pedal to the floor, it clears up instantly and takes off. The check engine light hasn't come on while this is happening. I'll be pulling the codes and putting a new fuel filter in it this weekend, but untill then, i'd like to see if i could narrow my search down a little. What do you guys think the problem might be?
