I own a 1997 Oldsmobile Bravada with a 4.3 liter V6. It has a
MAP sensor and what appears to be a MAF sensor too. The Haynes manual I have dosen't say anything about this engine having both but Auto Zone does have a parts listing for both MAP and MAF sensors. I just got my HHO cell up and going and I built a MAP enhansor using a schematic from this forum. I can manipulate the signal from the MAP sensor and get the engine to start "pinging" or "spark knocking" so I know it is working but wonder if I also need to be "chatting" with the signal from the MAF sensor before it gets back to the ECM. I read the MAF is a demand sensor so it gets what it wants. Is this true for the MAP sensor also?
