Electrical or emissions system failure can potentially cause a P0302 DTC to appear in some situations. Spark plug failure. Spark plug wire failure. The coil pack is not working. The fuel injector is faulty, unclean, or clogged. Cylinder compression is low. Plugging a scan tool in, Identify which cylinder is at fault if possible with misfire counts, using mode 6. There are multiple ways to identify where the misfire is located. Spark plug wires wear out after miles of service, which will have an adverse effect on the spark. Examine the wires for cracks, burns, and other damage. If your misfire only occurs when it rains, start the engine and spray a little water on the wires and see if sparks appear. If so, you need to replace the wires. The seven most common symptoms are listed below. 1. Loss of Power. You may notice a loss of engine power if there’s a misfire.
