2.2 Ecotec misfire
Monday, February 06, 2012 5:19 PM
2004 Saturn Vue 2.2 Ecotec cylinder #2 has weak spark . vehicle misfires on that cylinder , took coil pack and plugs out , put plugs in coil pack and laid them on top of the motor and #2 has weak spark . Swapped out with plug from another cylinder and that plug has weak spark. basically ruled out the plugs , just wondering since the coil packs fire 2 cylinders each you would think that 2 cylinders would have weak spark if the coil pack was bad so i'm leaning toward it being the ICM. Any Feedback????
