I'd erase your codes, drive around a bit same run again. If code 66 returns, you really need to check MAF signal voltage at the meter, and then down at the ECU between pin 9 and 50.
Should be around 0.5 volts at idle and increase towards 5.0 v the higher you rev the engine.
Testing at the ECU will rule out a bad wiring fault somewhere between meter and ECU.
Could be a bad meter, but I'd troubleshoot and test first before firing the parts cannon at it
When checking signal voltage at ecu do i do one pin at a time? Pin 9 then pin 50? Or i test them together? Not familiar with checking volts and measuring ohms. An i need the ecu harness actually plugged in right?
My apologies for such noob questions
