I have a 2004 Ford Explorer 4L 169k miles. The MAF is reading between 0.73 - 0.75 lb/min range and even fluctuated as low as 0.63. and as high as 0.89 lb/min. Is the range normal, if it’s not, what is the likely reason for it and what is the proper range? Thanks.
Here's information on MAF sensor testing:
