Thanks very much for the help. One more question, the original problem was that when you start the car in the morning the engine had a ruff idle for a few minutes and the red engine symbol would flash on the dash and then stay on even after the engine smoothed out. The first mechanic told me it was a single cylinder misfire code. After he found that coolant was going in the engine I guess he assumed it was going into the cylinder and causing the ruff idle in the morning and the code. Is this correct or is the ruff idle and check engine light something else unrelated to the LIM leaking? Thanks
