Technical Discussions
1

I’ve been having some issues with my car’s fuel injectors and I came across the noid light at Harbor Freight. I’m curious if anyone here has used it before for diagnosing fuel injector problems.

A Few Questions I Have:

  • Effectiveness: Does this noid light effectively determine if the injectors are firing?
  • Ease of Use: How straightforward is it to use? Any tips on how best to connect and read the signals?
  • Alternatives: Are there better options out there if this doesn’t seem reliable?

I’m looking for something that won’t break the bank but will still help me get my car back on the road. Any insights or personal experiences would be greatly appreciated! Thanks!

Great question, millerdavid! Always ensure your noid light is connected securely; otherwise, you won’t get an accurate reading. Also, check your battery and connections first before assuming it’s the noid.
