Well my friend has a set of RC 270cc injectors but we dont kno if they are saturated or peak and hold.... how can we tell? we tested them out in my 98 integra (had to switch to obd1 clips) and the car ran fine but i dont know if they are peak n hold or saturated ...he bought them used

 

Measure the resistance between the pins.

~2ohms = peak and hold (low impedance)
~12ohms = saturated (High impedance)

 

If you have a multimeter you can test them out of the car and figure out there impedence.

2-3ohms of resistance = Peak & Hold (Low Impedance)
11-13ohms of resistance = Saturated (High Impedance)

Edit* beat me to it!

 

Yea i got a multimeter at work illl check em out tomoro...thank you

 

If they are RC's the PL engraved on the side of the inj. is Peak& hold, SL means saturated.
