I have replaced plugs, wires and dist. with top of the line parts and am finding that when I am on the throttle, between shifts, the car will back fire from time to time.

Is this a timing issue? any thoughts?
Running a 1993 CIVIC EX 1.6 ltr.

 

Mine backfires all the time betwean shifts. Not loud but you can hear it

 

Mine does it too, but only when I get off the throttle and stay in gear. I really dont think its a problem.

 

i friend just got a new high flow cat. and it back fires once in a while, it's no biggy...i think it sounds cool
