check your oil and coolant too see that they are not contaminated (if they are, you need to replace your head gasket). check your injectors, to see that they are properly sealed/installed correctly. there's also the slight possibilty of contamination within the gas tank/entire fuel system. so check your fuel system first. there is also a good possibility of the car having a bad head gasket. if i missed anything, please post. it's been a long day. thanks
