injector ohms?

[Money pit Beretta]

Got board today and ohmed my old 3100 injectors. They were 12.0 to 12.2 ohms. Is this bad? What is the range of good to bad?

I think thats about right, I did Roberts when I was having fueling issues and they were all around 12 ohms. For me it ended up being a kinked fuel hose.

Cool thanks! I find it strange that the ohms still check out after 150k. The idle did smooth out with the new injectors.

Well they typically don't just die, they just get dirty with age, so they will still ohm fine but not flow anywhere near what they should.

I'm sure no one cleaned them before I got the car. I sure did, spent alot of money one Sea Foam.

12-13 ohms is the range that they should be in. And they will "just go bad"...been there, dealt with that.

And this is now why i carry extra injectors with me.

I was referring to age, injectors are more likely to get dirty before just dying from being old, or better said as they get miles on them the ohm's wont slowly increase, and the ohm check is a direct relation to the condition of them.
