The firing order for a 1979 Chrysler LeBaron depends entirely on the engine it has. Chrysler offered several different engines in the LeBaron that year. You
must specify the engine size (e.g., 2.2L, 3.3L, 3.7L, 5.2L) or the engine code (found on a sticker or tag on the engine itself) to determine the correct firing order.
Once you provide the engine details, I can look up the correct firing order for you.
