1990 Volvo 740 GL (non-turbo) with Regina Fuel Injection.

This morning the car started fine, but when I went to accelerate to driving speeds, it would not accelerate past about 20mph. No lights, and the only error code is 3-2-1.

I parked it and tried it again this afternoon. At first it was fine, but after stopping at a stop sign it would no longer accelerate past 20mph again.

With the pedal almost to the floor, it tops out at about 20mph. There is no backfire and everything seems normal.
Idle is fine with only minor fluctuations between 700-800rpms.

With the car in park, I can press the accelerator and the engine responds with no hesitation.

This ins't a bosch car, so there is no AMM.

Any thoughts?
