Hey guys, I'm new to this forum, and I dont know a whole lot about these newer magnum engines. I was driving down to Sacramento yesterday, and about half way there, my check engine light come on. I have a '99 Durango 5.2L, by the way. So I drove back home, plugged in my Hypertech programmer and read the codes. One code was displayed, P0204..........Injector Circuit Malfunction Cyl. 4. What does this actually mean? I called the dealer this morning to see if it's something I can fix at home, the tech. said it's not a faulty injector, and that they'd have to look into it more. I dont have a warranty anymore, so the service is coming out of my pocket if it goes in. Help me out guys. PLEASE.
