Hi all, So, I checked all the FI sensors and other peripherals. The idle valve, full throttle enrichment switch, checked all the voltages and resistance per Bentley. All checked out good. Checked the ignition timing. Swapped out the ECU, removed the catalytic converter. All didn't make a difference. I just filled her up and calculated I'm getting 8 mpg. This NEVER happened. Seems insane. Maybe she's starting to behave like her possible Detroit replacement. I am going to order a new AFM from Busdepot. Seems like a very good deal actually. It's the only thing I can see being bad, though I can't tell for sure that my AFM is bad. The spec in both Bentley and Haynes don't specify exactly whereabouts the resistance would be if you move the flap. It just says" varying voltage", but no more. As I move it around I get fluctuations between 1100 and 1600 ohms, but it doesn't steadily increase in either one direction. While it idles, the potentiometer arm vibrates, when I open the throttle, it gets steady again. I'll keep you all posted on what happens, hopefully the new AFM will make a difference.
