Hey guys, a few days ago i started my car (R33 GTST - RB25det) and noticed it ran pretty rough. so went into diagnostic mode checking everything until i got to checking coil packs and noticed no change in idle when unplugging cyl 6. so i replaced the spark plug and still no change. so i stuck a wire in the coil pack and held it over the valve cover and it gave a weak spark so i put that end of the wire on the spark plug and it did improve but just a little, the rpms jumped up and down from normal to low. what do you guys think? Just a bad coil pack or what? any help appreciated!
