I have a 3.8L motor in van 2 days ago it started running rough and burning tons of fuel. Ran trouble codes and got code # 27. While van on ramps and running I can see fuel leaking out of the tail pipe next to the motor from the donut ring. I lesioned to the injectors firing on they all sound good with no funny noises. I was thinking one was stuck open and dumping strait fuel into chamber with out being burned. What could it be?
