I'm thinking that this has already been asked but I can't seem to find an answer so I have to ask anyways. What Pids monitor the air/fuel mixture and/or MAF curve?? Thanks for any help.

Carnage, You can monitor Mass Air Flow Sensor Voltage and Airflow Rate From MAF Sensor in grams/second of airflow. As for A/F mixture you can monitor fuel trims in closed loop which are the correction factor to achieve stoichiometric A/F ratio based on 02 sensor feedback. Lambda equivalence ratio will show you the commanded A/F ratio, however that may not match what is in the exhaust if the calibration is off a little.
