Hi all i am new to the board i just recently aquired a 93 Z28 and need some help i tried the search but did not come up with anything. i am hoping someone here can help.
My problem is with the passenger side fuel injectors when i take the harness off the first injector the car starts to stumble, when i remove the harness from the second injector there is no change, here is where i get confused when i put the harness from the first injector on the second injector there is no change, and when i put the harness from the second injector on the first there is no change i know the first injector is working and the second is not is it possible the injector and the harness are both bad?? ant help will be greatly appreciated thanks in advance!!!

 

Due to the batch fire nature of 93s, swapping injector connectors may not produce the results you are expecting. The one you pull off and there is no change should be suspect. The resistance of the injector should be ~12 ohms. Even if it is, that does not mean it couldn't be clogged up.
