99gtstang

i left a post a few days ago and didnt get any good answers i want to try again.... my car 99 gt ... minor mods intake, pullies, exhaust....it wants to stutter, or jump almost like its skipping. Drives like a car with a coil pack going bad..... when i change gears... i can also be riding 80 for miles and i will get a kick every now and then... i replaced plugs last night.... with OEM...... ran fine until tonight started right back up????/ new plugs, boots, springs, No check engine light is coming on.... can the coil packs go bad without a light triggering???
