Injector resistance

[ca12los]

Hello all, I just measured the resistance of all 8 injectors on my '93 Ls400.
The manual specifies that 13.8-14.2 is acceptable, however, Mine measured 14.3-14.5
No biggie I am sure, but what would you guys say?

You should be OK; that resistance measurement will drop when the injectors are hot.

I would be concerned if the resistance was low, like 8-10 ohms, which would indicate a partially shorted coil, or very high, like 20-30 ohms or more, indicating a partially open coil.

You can do a functional test with these high impedance injectors by connecting them directly to a 12v battery. Don't hold them open more than a few seconds, however, because they'll quickly overheat without fuel going through them to cool them.

Don't try this functional test with low impedance (< 4 ohms) injectors as you'll fry them immediately. You'll need to put a resistor box in series with low impedance injectors to test them with a car battery.
