Ok, help me here...this is what I don't get about the wiring/connection possibility:
It's just a wire, correct? It simply transmits the signal from point A (MAF) to point B (DME). Like... all or nothing, I would assume. So if the wiring or connections were damaged, then the signal wouldn't go to the DME. Which would be the exact same as having the MAF unplugged. So I would think in that case you would not get MAF signals to the DME regardless of if it was plugged in or not.
Or are you suggesting that the wiring/connections could be damaged in a way that could somehow degrade or corrupt the signal from the MAF??

The terminals can be dirty, corroded or even loose. Just visually inspect the terminal contacts and make sure they are not spread making a soft or poor contact on the MAF connector and on the DME connector. If you have an ohmmeter, check the continuity of the wires from one end to the other. It doesn't cost anything but a few minutes of your time to rule that out or validate an issue.
