my car has been running rough lately. i'm trying to do an ohm test the injectors. i bought an auto-ranging dmm from home depot. i pulled the connector off the injectors. the injectors have three prongs. i get a reading on the two prongs on my left only. i got a reading of .6 ohms on 5 of the injectors. i didn't test the one under the balance tube. i read that the injectors should test between 10-14 ohms. it seems a odd that all the injectors are testing below 10 ohms and all are .6ohms. the multimeter seems to be working fine. any suggestions?
