Hello All,
I was changing the spark plugs on my car today (Nology Silver R4YS). she didnt seem to be sparking properly. Its ticking over, but no power....car nearly craps itself. I reverted back to the old plugs for the moment.

Has anyone used Nologys yet? just wondering if anyone does have these, do I need to reset the ECU? anything I need to know or should it just be a straight swap?

Thanks in advance :)

Misfiring is commonly caused by the three small wires that connect the the bottom of the coil pack on the front side degrading. The wire harness is too short, and the wires get beat up by the engine moving back and forth on it's mounts. Ford sells a replacement wire set you solder in place if you find damage.
