It sounds like the AF meter has an issue, either stuck full open or it is telling the injection control that it is wide open.
Here are the ohm numbers for testing it:
Connect suitable ohmmeter, Fig. 4, between terminals E2 and VS Resistance should be 20-400 ohms.
Connect ohmmeter between terminals E2 and VC. Measured resistance should be 100-300 ohms.
Connect ohmmeter between terminals E2 and VB. Resistance values should be 200-400 ohms.
Connect ohmmeter between terminals E2 and THA (intake air temperature sensor).
At ambient temperatures of (-)4°F, resistance values should be 10,000-20,000 ohms. At temperatures of 32°F, resistance should be 4,000-7,000 ohms.
At temperatures of 68°F, resistance should be 2,000-3,000 ohms.
At temperatures of 104°F, resistance should be 900-1,300 ohms.
At temperatures of 140°F, resistance should be 400-700 ohms.
Connect ohmmeter between terminals E1 and FC. Ohmmeter should read infinity.
With measuring plate closed, check resistance between terminals E1 and FC (fuel pump switch). Ohmmeter should read infinity. Fully open plate with a screwdriver, then observe ohmmeter. Resistance should be 0 ohms.
With measuring plate closed, check resistance between terminals E2 and VS. Resistance should be 20-400 ohms. Fully open plate as described above and observe ohmmeter. Resistance should be 20-1,000 ohms.
