Bank 1 seems to be running slightly leaner than Bank 2 everywhere, and nearly maxes LTFT's at idle. Switching sensors actually helped for a few hundred miles, but same problem has come back. Just tore off the intake manifold and headers and checked all vacuum lines, kind of lost. Only possibility I can think of would be an injector, but I would think that the problem would be worse up top rather than at idle. Here's my last log. My wideband should be here within the next couple days, which bank would be a better option to install the wideband if I can't tackle this issue?
