My s14 (5spd) feels like it runs perfectly but the CEL started blinking today while driving. The car didnt bog/stutter/lose power it felt fine. I shut the car off restarted it with no problems and the CEL stayed lit. I checked the codes and im getting code 34(knock sensor) code 77(rear o2 sensor) and code 103(park/neutral switch). I have done a search on the individual codes and how to fix them but I am wondering what a blinking CEL is all about?
also, is it possible that an o2 sensor malfunction would trip the other codes?
i hope this is going to be a cheap fix...
