I’m not sure what to look at next. I’m throwing bank one and two lean codes. It’s not the maf sensor. I don’t believe I’m having a fuel issue but I may get the pressure checked. Can someone give me tips on using a multimeter to check the maf plug. I spliced into my maf signal wires for my mafterburner and had my ecu out recently and I’m wondering if one of the connections is messed up.
