    06 lly knock at 1300-1700 rpm

    I thought so at first, but when I unplug the connector and clear the codes it still knocks really loud. I called a local tech and he said that It really sounds like the injector is stuck open. I ordered it from Pensacola injection and he said he wouldn't ever deal with that company. So I have a...

    06 lly knock at 1300-1700 rpm

    Okay so I put a new injector in today. Went to start the engine and it has a terribly loud knock now. It's throwing 2 codes which are P2149 and P0208. We broke the outside of the electrical connector when plugging it in, but the actual plug part still looks fine. Do I just need a new pigtail or...

    He did a balance rate test and these are the results. He said he bets it needs a new #8 injector. Sent from my iPhone using Tapatalk

    I know I can get a very nice snapon scan tool. Hopefully the guy that owns the scanner knows about the motor. Sent from my iPhone using Tapatalk

    06 lly knock at 1300-1700 rpm

    This is probably a stupid question, but how do I test to see if and which injector is bad? I've also read that sometimes the connectors just go bad. How would I know if this was the case? I have the day off tomorrow and really would love to get the problem diagnosed and parts ordered. Sent...

    The sound isn't as prominent when I step on it really quick and go all the way through the rpm range Sent from my iPhone using Tapatalk

    Another question- is it terrible for me to drive it around town? It's the only vehicle I own and have to get to school everyday. Sent from my iPhone using Tapatalk

    Yeah there is no white smoke at all. The motor only has 90k on it is the crazy thing to me. I just bought it and the knock started about a week after I bought it. Haven't even made the first payment. Hopefully I can find a good mechanic to take it to. Sent from my iPhone using Tapatalk

    06 lly knock at 1300-1700 rpm

    I have a 2006 duramax that has a knock at 1300-1700 rpm only when warm. No white smoke and only mods are a k&n filter, and turbo back exhaust. Also have a bullydog programmer on Eco tune. It runs and drives fine. Started about a week ago when I was going up an incline. Been doing it ever since...
