My first impression is "no", and here's why I think that. 1985 - if that's still a CIS injection system (anyone know? With the round plate, not the air mass meter?), then the amount of air going through meters the amount of fuel which is let through the valve. Unless you *also* were to decrease the fuel pressure by 25% (causing who knows what else to go wrong), then the fuel destined for your bad & shut down injector, would just end up making the others 33% over-fueled. If it's an air mass meter type system, maybe, *maybe* you could just pull the injector's electronic connector. I think that it would be happy to tell the injector to open, but it just wouldn't. Not sure what the long-term effects of running this way (other than the obvious loss of power and smoothness), but I can't imagine it'd be real pleasant. Which injection system does your car have?
