    I don't have an answer, as a noob owner. However, at least when the officer asks "Do you know how fast you were going?", you can honestly say "No sir!". :)
    I'm sure one of the experts will chime in.

    Sounds like it might be the pickup /sensor feed from the front of the engine. Part number 116987.

    what you mean is the rpm sensor and the TDC sensor, has nothing to do with speedometer or odometer

    Jim, sorry to hear you have a minor issue and knowing you like things perfect I can see how it will bother you.

    I had the same issue with the my TR. It was the sensor at first and then it was the speedo acting up and after several attempt of having it speedo repaired, I had to replace it. Lucky for me, I found a complete cluster within near same miles on eBay. I purchased it and install it and the problem was solved. When I sold the car the original cluster went the car.

    You might want to call The Auto Gallery and talk to Eric. He might have one laying around.
