So, I ruined my stock H22 igniter while wiring my dizzy into the ek harness. Melted it. So I gutted my old d series dizzy and the igniter looked identical to the h22 igniter so I put it in the H22 dizzy. It ran fine for the first drive. Today I drove the car for an hour and as the engine got hot the car started to misfire and run like ****. Are D series igniters not interchangeable with H series although they look the same? It idles rough, and when you put the pedal down more than half way it cuts out really bad in any gear.
