My 1-4 light was comming on every so often then going out intermentaly. I discovered my water level was low. Filled it up and the problem went away. I highly recommend, if you havent do so, doing belts and hoses, going thru the complete cooling system. Once you are certian you have a good timing belt, water pump, and no leaks, these cars are pretty difficult to screw up in a major sort of way. Sounds to me like you have just a few little things wrong with it. I've just had min about a month. I intend to go thru it from top to bottom, starting with the timing belt and cooling system. These cars in my opinninion are a phonimal deal. But the rality is if you intend to own a race car, (even a street legal one), then you can resonably expect to work a little harder to keep it right.
