I searched around and couldnt find how to check injectors ohms for the impedance. I seen a site before shows how to clean them and inspect them i have a craftsman digital multimeter but dont know what setting also.

 

If you are trying ot check whether they are low or high impedence you simply put your multimeter on ohms (looks kind of like a horseshoe). Go accross each tab of the injector and see your reading. If it is 1-3 ohms they are low impedence and 5-8 is high I belive. Don't quote me on the exact range but it is close.

 

Yeh i just figured it out i had both kinda of injectors so i can see the diffrence. The low impedance injectors turned out to be 026 and the high impedance were 126 that on the 200 ohms reader it has different settings goes up to 2000k and the 200 is the lowest i think that is 2.6 ohms and 12.6ohms which is right. + - .1 ohm
