Recently did new coils and spark plugs. Upon inspection I noticed I didn’t have any coolant in my reservoir for my heat exchanger. Therefore added some royal purple ice and proceeded to drive it and noticed misfires and fluttering as if combustion was effected. I checked the coolant and it’s empty. Any thoughts or ideas helps pls.
