Blue colored smoke indicates burning engine oil.

Also check the fuel return lines between the injectors. Any leaks can allow air in, and that can also cause a miss. A compression test is a good idea. It may have a stuck or broken ring, especially since it sat so long.

How does the engine run at normal operating temp?
