what "I" would do is to turn everything on and set the idle at THAT point, like it says in ever manual I have read dealing with the L-jet and D-jet.
Before anyone tries doing this on an L-Jet car note:
This is not the proper method of setting your idle speed/timing with L-Jet. Proper method is with both vacuum advance and vacuum retard disconnected (tubes plugged as not to read false air) from the distributor, 7.5º BTDC at 850±50 RPM.

The FI system is irrevelant in this case.
You win the dumb L-Jet answer award kiddo
L-Jet is an electronic injection system. Every time an injector fires you use power. Not sure of the amperage per injector, though. No accessories on you will have the following pulling power:
Starter (on startup)
ECU (brain)
Fuel Pump (zrrrrrrrrrrrrrrrr...)
Guages: Tach, warning light, fuel guage, oel pressure, clock, voltage meter, stereo
Dual-relay unit for injectors
Finally, the injectors.
When you turn the headlights on it creates a significant draw on our (45 amp?) alternators. You've got two beams pulling up to 30a each, not to mention all of those running lights.
My idle drops as well, too. It's because you have an electronic fuel injection system and an alternator that can barely put out enough current to supply the draw. If you turn on your foglights and/or heater at the same time you'll see the voltage guage hover between 11/12, maybe sit right at 11 with the brake lights on.
Solution: Higher output alternator, or go LED running lights with an electronic flasher unit. But you've still got both of those headlights pulling a lot of amperage each...
