So, Coolant flush with standard green coolant, and stock coils w/ new, Irridium(?), plugs...got it. And you guys mentioned Dex-Cool turning to mud once exposed to air. This, I'm thinking, could be signs of a leak since I have also noticed the coolant level low from time to time despite the fact that there is no trace of a leak on the ground. So, more than likely I'll need a new LIM gasket as well? And I also want to add, thank you all for your help. I'm really fortunate to have people out there like you all that love Grand Prixs as much as I do and hate to see them go down without a fighting chance.
