Sirs, I have a problem that is running me nuts. The van in question has a new moter with less than 25000 miles on it. Well the engine light came on as P0304. So I had the plugs changed alone with the rotor, rotor cap, plug wires. This had no effect so I had a compression check and all seems ok. The next thing I changed was the no. 4 injector. Still no change. The motor idles rough and the gas mileage has dropped. The next thing I did was to remove all the injectors and blew out the fuel lines. I replaced all the injector gaskets and the intake cap gasket. All still the same. Rough idle. Please HELP!

Have you checked the injector to see if there is power to it? If not then check to see if there is power to the injector and let me know what you find.
