Whenever i leave my car for a long period of time and come back to turn it on theres a rough startup as if something is clogged in my exhaust.After maybe 2-3 seconds everything goes back to normal and my car sounds fine.Heres some stuff thats been happening
1.I can smell coolant everytime i turn on the car(also when i use my heater)
2.I have to fill my radiator with water cuz its disappering(i have no idea)
3.that rough startup

Maybe everything will go away when i get my jdm d15b installed this weekened and also my car converted to manual(thanks Emerika).For now i have no idea whats going on and i just hope my car can make it to friday
