Fuel Injectors..."Low or High" Impedance

?????????

Hey George whats the difference between high and low impedence? What does that mean?

Thanks, Dillon
 
The high or low impedance is reffering to the electrical load the coil in the injector places on the output drivers in the fuel injection circuitry in the ECU. Our ECU's need high impedance injectors.
 
Could this be the reason why my check engine light came on? I have an 89 XR7 that i changed to 42# injectors and now it reads code #98. Can anyone give me some insight?
Thanks, Steve
