so my mustang has been having issues with the engine sputtering under moderate to heavy acceleration, i have changed out the coil packs, the spark plugs and put injector cleaner in the car. each thing i do helps the car out a little but it still wont completely go away. it only does it for about 2 seconds after i give it gas then it stops as if nothing is wrong at all. any ideas?
Thanks,
Brannon
