What would cause a car to run so rich it smokes out the whole neighbourhood in a matter of seconds. I put new plugs in and they were fouled after only minutes of running. The car will start but only with your foot held to the floor, and it does not run for long. I do have a very leaky injector seal but I don't think that would cause this. I installed a cam myself and have now taken the car to a mechanic. He is looking for posible causes.
