OK maybe you guys can help me. I was trying to clean out some stuff from my garage and found 2 sets of injectors, I know 1 set is obd0 and the other is obd2 but I have know idea which one is which . I there any way to tell them apart? markings etc...

 

do u have a obd0 or obd2 car try plugging them into ur car ohh and i belive the ob2 have a notch inside the injector on two corners not positive though

 

you can usually tell obd0 injectors plug in to white plugs but the o rings on the top of the injector are like an olive green

 

a simple way is to measure the resistance of the injector.. 9-14 ohms is obd2, 2-4 is obd0..

those numbers might not be 100% accurate, but you will be able to tell the difference from the resistance.

 

Thanks, I think I can figure it out from here.

 

or if your super lazy post a pic..
