Overheating

You need to get a head check done, this is a quick and simple chemical test to determine if there is any combustion leak into the cooling system. This can indicate a blown head gasket. A compression test on the misfiring cylinder will also be a help and a visual indication of coolant in the cylinder is a dirty brown stain on the spark plug. Start with the head check a mechanic can do this test in just a few minutes, often while you wait. Post back with the findings for further advice.
