Default Running rough

95 Bonny SE.
This problem has been going on for months. The car will run like a champ then some days is running like crap. Runs like is missing fuel or air or both. I changed the plugs, cables and checked all wiring and coils, also checked for vacuum leaks. The car is eating all the coolant, I know I have to change the gaskets and I will do it next week. Any help will be appreciated.

Fix the gaskets and I bet the car will run much better. After you get the gaskets fixed, change the plugs, do an oil change and then let'* see how its running.
