The one that sticks out like a sore thumb is causing the problem. If you do an ohms check on each plug, do the comparison game. If you want to get really picky, seemingly good spark plugs might have different internal resistances. Also keep an eye on whether the plugs were torqued properly and the right amount of anti-seize is used, since globs of it can cause misfires.
Do not get brainwashed by the parts store voodoo that you can use different metal or brand plugs. If you find out it is the spark plug to blame, make sure that the OE spark plug was installed.

Simply hook up to the spark plug wire you put in series between the COP and the plug like the way you are used to, and you have your secondary waveform!

How do I do it? Install an ignition jumper wire that you can make up using a spare spark plug wire. What does it do? Allows you to diagnose if a misfire is plug or coil related. Trick #2: Getting coil-on-plug (COP) secondary waveforms Never divert the spark for more than three seconds at a time to avoid damaging the catalytic converter.ĬAUTION: Never touch the hose (if you do, it will be a very shocking experience). Use a grounded probe or test light to attract the spark through the hose. This allows for easy cylinder shorting to identify a weak or dead cylinder. How do I do it? Place a short piece of rubber vacuum hose between the coil pack tower and the spark plug wire. What does it do? Identifies which cylinder has the ignition-related misfire. This month we will cover ignition diagnostics without getting into interpreting the waveforms. However, we want to give you techniques that you can use now to diagnose cars quickly and make money in the process. Ignition diagnostics is not that complicated. Suffice it to say, ignition diagnosis is becoming a lost art. Many repair shops don’t even use a lab scope. Tune-ups are once every 120,000 miles on many vehicles.
Because there was so much money to be made, shops invested tens of thousands of dollars in “big box scopes” to diagnose all of the ignition problems that were common in the day. Years ago, vehicles required annual tune-ups. “Jerry” Truglia, Kevin Quinlan and Adam Varney.) (Vehicles diagnosed and waveforms captured by G.
