Running out stuff to try,,, I have been fighting smoke at idle issue for 3 mouths. I have installed 2 sets of injectors ipc valve then a cp3 pump. Nothing seems to help, runs great down the road but stop at a light and gray smokes takes over. I know balnce rates don't tell the hole story, but both sets have been we'll within spec. In fact one set has been installed on a 03 and runs perfect. Out of ideas and money,, lol any advice?
LB7: White smoke after injectors and cp3 pump installed

Yes after first set of injectors, forgot to mention you can smell raw fuel at tail pipe. I have installed Kenndy fuel pump and fuel pressure relief block off, it's at the dealer now checking actual and desired fuel pressure. Acts just like bad injectors, just don't see how two sets
most people won't recommend changing cups unless one lifts out with the injector.
If there was a compression problem, it would show up in a balance rate.
And you couldn't pay me to run someone else's used injectors in my truck. ESP on an lb7. What do you consider well within spec?

Who is DCS? I have tried Remans from very reputable places other than genuine Bosch and never had great luck. Balance rates won't be as low and they won't last as long. I have helped out more customers than I can count with trucks that they put injectors from _________ (you name it) in their truck and immediately had issues. Sounds like you need to take it to a reputable and experienced Duramax shop and have it figured out (and I wouldn't consider most dealers to be either when it comes to Duramax work). Do you consume oil over time? Do you consume coolant over time?
I believe there was a post on here not to long ago that GM is now installing both Pensicola and Bosch remans during injector replacements in trucks. If I can find the post I will tag it. The only ones I trust are from Bosch themselves. Especially in the LB7.
Sorry but :roflmao:
Why would GM buy injectors from a small shop that has a bad reputation when they obviously buy direct from Bosch? Who do you think they bought the millions of injectors from that went into the trucks originally? Even if they wanted 3rd party remans they would buy them for a bigger place that chain stores are buying from like Dipaco.
I don't remember anyone saying they got them from Pensacola, but supposedly Bosch told more than one person that they do not supply GM their LB7 injectors anymore. Here is the thread: http://www.duramaxdiesels.com/forum/showthread.php?t=58696
