When TFI modules go bad, Heat causes the circuits to expand and loose contact. Hence, the miss under heat conditions only. Once it cools off, the circuits contract and no more miss. Eventually, it will fail completely. The spark output is controlled by the TFI.
When you remove the connector from the TFI, you need to push inward then pull the connector out.
