Oiwa Garage Tech Note
"A coil that fails when hot will often test fine cold - heat-soak is the giveaway. Fit fresh plugs and wires with it for a clean ignition system."
Frequently Asked Questions
Does this coil need programming or a reset?
It is a direct plug-in; fit it and start the engine. No programming.
Will one weak coil affect the whole engine?
Yes - a failing coil causes misfires that hurt economy and can foul plugs, so address it promptly.
How do I test the ignition coil?
A coil that fails when hot often tests fine cold, so diagnose it warm. You can measure the primary and secondary resistance with a multimeter against spec, or swap in a known-good coil - if the misfire clears, the coil was the cause.
