Inspect and transform the spark plug wires if important. When spark plug wires are routed in the distributor for the cylinders, it is actually quite essential they usually do not physically touch one another. This could result in a phenomenon recognized as “crossfire”, whereby the electrical energy flowing by means of a single plug wire could in fact “cross” to the adjacent wire, creating the engine to misfire. If they’re all separated and appear fine, it may very well be time to substitute them that has a new set.
