Hey,
I have a 1997 Galant VRG GDI 1.8 4wd. Im also having fuel problems as well as oil comsuption. What I know is that the air to fuel ratio is way off. Pumps more gas than it should, the gas doesnt burn completely and it sticks to the cylinder and mixes with the oil. Thats the oil consumption problem, as for the gas im still checking the O2 sensor and anything else that might make this problem go away. I have a GDI repair manual in English if you are interested, uf you have any answers or anything that might help me out please let me know. Thanx
