Having a rough summer (as referenced in another thread) engine-wise. Latest issue...I pulled the injectors on both engines on my 06 340. Had them serviced and while I was told they were pretty rough, they all came out good. When I put them back in today...upon starting the engines there was a heavy gasoline sheen from both engine exhausts. I was told they tested 70cc at 40psi. Both engines ran previously without this issue. Thoughts?
