To complete this step you will need entry to a timing light, or just have a store do it for you personally. Mark major dead-center about the reduce pulley (the crank pulley) with chalk and connect the timing light to your quantity one spark plug wire, then level the timing light in the pulley using the engine operating. On older model cars the distributor is often turned somewhat for the left or proper until the mark lines up (at prime dead-center) using the flashing strobe from the timing light.

This might lead to a phenomenon identified as "crossfire", whereby the electrical energy flowing via one particular plug wire could actually "cross" in to the adjacent wire, leading to the engine to misfire. If they're all separated and seem fine, it could be time to change them having a new set.
Change obd2 scanner the distributor cap and rotor, if needed. Take out the distributor cap and inspect the terminals beneath each plug wire port. If they appear broken, burnt, or missing, it is actually time for you to replace the cap itself. These could be uncovered on the car components retail outlet also, and therefore are rarely very highly-priced. If one particular or far more with the terminals are damaged in any way, a misfire could come about.
