You have a bad ground for the air flow meter,check the black/white wire for a break.
I was thinking that myself so I cut about an inch off of the old plug-in installed a brand new plug with pins just to make sure I had solid connection
Where does the mass airflow sensor ground go once it goes into the harness do you know by any chance maybe I'll track back further
Are the camshaft sensor and mass airflow sensor on the same ground
Probably to a engine block ground,where,not sure.
Hmm you need a diagram firstly then check the colors of the wires concerned yeah you need to follow the wires be unwrapping the tape hecking for crorosion discoloration current won't travel over dirty wires. Lol
Put a new ground on, splice into the black wire and ground to block or some other ground point.
GuruWBGZF did your ever figure this out I have the same problem on my 1997 suburban
