Replaced entire throttle body, vacuum lines, MAF, And o2 sensor. Stil runs like shit. Wont go over 4k with maf plugged in, I get better gas mileage with maf unplugged. Could it be wiring issues? I'mm also running with my IAC unplugged, With it plugged in the idle surges horrible, Worse than with it unplugged. This idle is driving me crazy.
