Re: Can't get Oxygen Sensor reading

Then why is my waveform so screwy looking? It's the same on multiple vehicles, so I don't think it's the way I connect to the sensor; rather, it's probably a software configuration error. Please advise.

It appears that the parade is constantly moving across the screen, so how can I tell which is cylinder #1? Is there a way t...
