    I had my injectors tested last week and they were between 50-450 PSI below pop level, so I had them replaced with brand new Bosch (stock) injectors. I installed them and torqued them to 50lbs. None of them are leaking and I have fuel all the way up to the injectors, but I’m still not getting any...

    My 2006 2500 was sitting for a bit while the transmission was being built and replaced. I also put a brand new lift pump on it and it started and ran just fine. I took it for a drive and then it seemed like it started to miss. I attached a code reader and got a P0306 cylinder misfire code. I...
