Just pull the vacuum line off of it and check to see if there is fuel in it. If there is fuel in it the regulator is bleeding fuel directly into the intake. I can almost guarantee this is your problem. Simple to replace also. Approx $100 bucks at the dealer.
Yup, that was it. I pulled the vacuum line off of it and fuel ran out. It is a little thing, I was expecting something bigger. Any tips to replacing it? Looks like one metal clip and a vacuum line. Anything else I need to know?
