General Maintenance & Repairs - Pops and misfires at very light throttle

This only happens if I have the pedal pressed very lightly. Like a little more than the weight of my foot on the pedal. The car bucks and I can hear a popping sound coming from under the car. All I have done so far is reseat the plug wires which didn't help. Any ideas?

are you sure its missfiring?....the way these cars fuel systems are set up...an how the fuel cuts off, is that when you go back to the gas ever so slightly you will get a popping sound out of a aftermarket exhaust....check and see if you have misfire codes....
