Well I just got my 87 IROC on the road. I have noticed after about 15 minutes of driving the car will get a SES light and the code is 44 for lean oxygen sensor reading. now I'm hear a particularly loud ticking noise coming from the injectors. Now I know that the injectors are supposed to be noisey and know for their ticking but I just have a feeling that my car might be dying at a stop at times because of a bad fuel injector? Any opinions would be awesome!

 

Did you ever find the problem for this?

I am having the exact same issue.

Thanks,
Kirk

 

Actually Kfus I just fixed it yestarday! I yanked out my ICM (ignition control module) put in a new one. then I redid the timing and set it for 6 degrees. After I reset the ECM and it hasn't died once at a stop or a red light. Definitly try that if you got about $40 to shell out.

 

Thanks for the reply, and congrats on finding the problem, I know that feels good.

I have changed that out, but I did not change out the knock sensor to go with it, I will try that next.

 

hey 83 maro how did you go about doing what you did. did you replace the ecm and in explanation form what exactly did you do. i've stressed so many options i'm startin to feel like a 'tard.

 

Found my problem, like usual it was a simple thing. My PCV valve hose had a split at the manifold, causing a vacuum leak.

Thanks!
