Mastering the Art of Normal Sensor Readings

The MAF readings seem choppy as RPMs increase under load. Not sure if this is normal or not, but I'm chasing a performance issue during acceleration at low ... One which is pre-cat was about 1.5 (up to 2) volts on idle. I've been told that lambda probes should not give more than 1 volt, so I've decided ... Actual grams per second, voltage or frequency readings should come from the MAF signal data on the scan tool at specified rpm settings. Example 1. A good MAF ... Ever since I've owned the car its also felt sluggish compared to my 2010 318D. Does anyone know if this MAF reading is normal? Thanks! Sam. 1999 - 2006 (GMT800) - MAF sensor reading - I'm trying to diagnose my maf sensor. I conducted a test w/a DMM and the voltage was 1.96 I then ... I picked up a bluetooth doohickey and Torque app, and I noticed that on my 1996 3.4 automatic, my O2 Bank 1 Sensor 1 is reading between .3V and ... Reading for a good sensor should fluctuate from 0.2 to 0.8 with 0.1 being (lean) and 0.9 being (rich); and average 0.45 volts (balanced). O2 sensors should cycle continuously between 0.2v to 0.8v and back to 0.2v about once per second. 2.67v isnt right. Could be a vacuum leak, ... My MAP pressure is around 11 in/hg at idle. Not sure if that's right or not, but my car is running super lean. Hey I was just wondering what normal voltage should be for o2 sensors mine seem a bit low. Downstreams tend to hang below .4v usually around ...
