300TE acceleration problems

My 300TE is experiencing very rough running upon acceleration but only when it is warmed up. I just put in a new fuel filter and injector cleaner/conditioner. The problem has not occurred since last summer. At that time it seemed to only occur when the weather was very damp. The OVP is new, the fuel relay is relatively new. When it cut off on the boss (my wife) the other day, it sounded like it was kicking back and backfiring through the intake when I was trying to start. Now when warm, it idles fine but if you punch the accelerator, it seems to want to cut off.

Any thoughts. I'm a new member to the group.
