Got a P0351 code. Examined coil pack and found numerous cracks. Replaced coil pack. Still runs rough. Weak spark at #2 cylinder coil tower; possibly also at #6 (same internal coil.) Test light shows voltage at input for coil and pulsing signal at all wires from PCM both positive and negative. Oddly (to me) the signal pulse for the #2/#6 coil seems much brighter than the signal pulse for the others even though the secondary spark seems weak. Resistance for all three coil secondaries is around 11kΩ each.
have the same problem?
