Another question: the wiring diagram of my 2.2 litre 4 cyl. Sonoma shows that the 4 fuel injectors are wired such that #1 and #4 are in parallel with each other and that #2 and #3 are in parallel with each other.
This is the "Iron Duke" not the "2200", correct? The 2200 has SFI and as far as i know does fire the injectors one by one. There's nothing wrong with batch injection though. Due to intake manifold resonance, air is still moving within the runners even though the intake valve is shut, so there's no worry of fuel pooling up. I've got a V8 Porsche in my driveway that runs 100% injector duty cycles constantly. It varies fuel delivery by modulating the line pressure.
