i pulled my spark plugs out today and the tips looked normal other than a light green tent.. so im guessing its coolant....

 

I doubt its coolant, is your car hesitating or boging, or doing anything abnormal?

 

sometime its hesitates i thought it could be the vavle gasket

 

What exactly do you mean by "valve gasket?" Coolant present during the combustion process leaves the plugs very clean (often times with a white residue) due to the steam cleaing effect of the coolant turning to water vapor.
A light green or red residue is often caused by the use of fuel additives or the additive in the typer of fuel that is used. Nothing to worry about.
