Hello everyone, hoping someone will be able to help. I've recently installed engine and I'm getting lean codes on both banks. At first thought maybe MAF sensor, I replaced that along with egr valve and dpfe sensor. Then I went back over the valve cover and intake gaskets with a fel pro set this time still getting codes. I have also replaced fuel pump and filter. I have only drove about 5 or 6 times to test drive. Today I noticed the right port of my new DPFE sensor melted. My research leads me to believe I may be getting back pressure from the exhaust. Has anyone experienced anything like this before?Could this cause both banks to run lean? Also went back over fuses (which I have already tested and replaced bad ones) and noticed now I'm not getting any juice to fuse port #13 which my manual says it's for the heated oxygen sensor, egr vacuum regulator, evr solenoid, camshaft position sensor, and canister vent solenoid. Any help would be greatly appreciated. I've replaced alot of stuff, at this point I'm just throwing money in the wind. Oh yeah Happy Easter!
