Yep. Brown = low impedance TII. Red = low impedance NA.

Are the connectors rounded? Red rounded = high impedance TII.

No...NA injectors would make the car run lean, not rich. What is the part number on the unit?

12MPG city isn't too bad...

Yes. All 87.5 + are high impedance.

Low-impedence requires resistor pack.

hmmm what about purple ones? my non-running 88 has the resistor pack, 87 block, and high imp injectors.


think thats why it doesnt start for more than .5 seconds? too bad my car is at the dealer and i cant try unplugging the pack

Purple are actually the early Zenki turbo 550's that are low impedence. These turn brown or tan due to discoloration of the plastic.

Running high impedence injectors with the resistor pack should still run.
