i have a 92 mustang gt,,,,and i just changed my spark plugs and my wires and my distributor cap on it,

and now when i step on the gas hard,i feel and kinda hear a poping sound or hitting sound under the car i think its coming from, i never heard it before i dont belive, i only notice it after i changed all the plugs and wires and all that?.

does anyone know what it could be or what i should loook for,, oh i also changed the feul filter.. and i filed my transmission fluid up cuz i got a leaking,,so if anyone can help i would love it

Do you still have the old spark plugs and wires?

did you make sure all the boots seated correctly, plug gap, firing order, and possibility of cracking the cap upon install?
