Hi guys so i have a 1997 EL ford faclon been running fine but rough ti start the first time of the day but anyways i decided to cut the baffle off and put a straight pipe on it so then i drove it for like 40 mins and it ran fine then i toke a corner put my foot flat and would just splater and backfire but then i could go quarter throttle and it goes fine then i drove it today and its worse not even idealing properly anymore so i changed the spark plug leads because they were badly damged and arking out bad and didnt make a diffrence so look at the disreptur and its brand new look at the coil pack and it is also brand new so you fellas have any idea on what i should do thanks???
