My wifes Town and Country has check engine light on. The code it p0306. I know it's a #6 cylinder misfire, but I can't figure out why it is misfiring.
The engine light is on. P0306. I've changed the plugs, plug wires, coil pack, and fuel injector, and the light is still coming on. I don't know where to go from here. I thought maybe fuel pressure was low and because the #6 cylinder is the last one on the fuel rail it's not getting enough pressure, but I can't figure out how to test it.
There is no scrhader valve anywhere. I've had the fuel rail out when I changed the injector and there isn't a valve on it to hook a fuel pressure gauge to. How do you check fuel pressure on these engines and is there any other ideas as to what could be causing the misfire?
