2006 Expo MAF Problems, I think??????🤔
Connected my Foxwell NT630 pro scanner up and went into Live Data and drove about 60 mi or more on the highway. When reviewing the MAF data @ idle it read 0.02 lb/s (756 RPM's) and when driving @ 60 mph / 1460 rpm's it elevated no higher then 0.16 lb/s then dropped down to about 0.03 while still at 60 mph. Now my question is "what should my MAF read when viewing it in "Live Data"?🤔

Can you change the data in the scan tool? reading pounds of air a second I am not to use to. It should read grams a second. I guess we could convert it over but my mind is not what it once was. Any driveability issues or codes?

No codes are being given, and I have no stomping power. It seems like it's taking to long for the transmission to switch gears. But, when it shifts, it shifts with such beautiful grace.

That's 9 g/s at idle and 72.5 g/s when driving. Sounds normal to me. Lack of power can be many things, the obvious first question is if you have done the usual maintenance, like changing filters and replacing fluids and such. How many miles does the truck have? Has the plugs been replaced?

Generally not, unless it affects the O2 sensors. Depends on the leak I suppose, and there would probably be a DTC set if there was something severely affecting the O2 sensors. If the history is unknown, I'd check the usual suspects like plugs and filters and so on. If no DTC is set, it can't be a serious fault, but something like a bad air filter or fuel filter does impact performance. Air filter is the easiest to check, if you haven't done that already.
