The other day I was changing my oil and noticed that the oil smelt like fuel. So I pulled the injectors and replaced all of the O rings. Then changed the oil to eliminate any contaminants. This morning I pulled my plugs to see how they looked, and they were covered with carbon again, after a week. I barley drive the car because my work is like a half a mile away. I also noticed that my Fuel pressure gauge was on zero when I pulled my plugs, So i'm going to run a bottle of 44k through it and see what happens from there. Any info would be of great appreciation.
