well the CEL is from a random cylinder misfire. Appearantly Bosch Platinum plugs are a no no in turbo cars. I am not sure what is causing the collant to roll back into the overflow tank but i will try to find out. Could a bad headgasket cause this to happen?as the car cools the reserve tank empties out with alittle less each time which would mean my coolant is dissapearing. I am hoping thay the radiator cap will resolve this problem.
