I had a diagnostics done, and they related that I need 4 new fuel injectors(91 cvevy z28 convertable). I am going to try an change them myself, but how will I know which 4 needs to be shanged?

If you have access to a DVOM you could ohm them out...should be right around 12.5 ohms for a stock Rochestor or Bosch unit. If they all ohm out ok, try pulling the plugs and taking a look at there conditon, if 4 are running lean, or on the other hand 4 are compleatly washed clean then you have your culprit.

Take care,

Thanks Eric, will look at the plugs tonight.

 

No problem
