ok so i'm more than likely going to pick up an 04 duramax this weekend. but the dealer is fighting what they say is a fuel issue. he didn't want me coming down and looking at it today cuz they didn't figure out what it is yet. but i came and looked at it anyways. for the price it looks and drives like a great truck until it cuts fuel and you can't drive it. around town it was great at 25 mph. but once i tried to get on it a little more it shifted hard and then wouldn't go any where it sputtered for awhile then it went finally. it did it again wen i was almost back to the dealer. he said it was embaressing that it was acting up duringa test drive but i told him it was fine you told me it had a sensor issue before i drove it. he says the tech pulled some fuel reg. sensor code off the pcm and there going to fix it tomarow. my question is does this sound like what is going to fix it or could it be the injectors that are still under warranty. or a really bad fuel filter? diesels are new to me but its pulling all the fuel wen your trying to get on it and it just idles/sputters trying to go.
