I ran the pump with the gas line disconnected and it ran clear gas. I changed the filter again. Now it is running lean right when you pull away and the car stutters a little. It runs fine otherwise.
I read that you can clean the injectors at the fuel rail, but I cannot find a product or company that sells the stuff to the public- its a small tank that you hook to the fuel rail, fill with a cleaner, disconnect the fuel pump, and when the car stops running they are supposed to be clean.
