    Engine continues to run after key removed? S52 OBD1 Swap

    Just took my freshly swapped E30 for its first drive, strangely when I parked it and removed the key the engine continued to run for about 3-4 seconds before shutting off. I have since drove it around the block 3 three times and the problem persists.

    Who did your C101 wiring? Also, when it dies does it sputter or does it sound like a normal car turning off.

    I ask because if someone wired the ignition switch/switch power wrong, the ECU/ignition could get power to keep the car running until you run out of fuel pressure from the fuel pump turning off with the key.

      make sure you didn't reverse polarity at the battery junction terminal. make certain the brown wires are going to ground and not 12v source.
