Well in essence, something is killing O2 sensors in my car. I opened another thread on it
here. I suspect it may be a fuel injector but don't have unequivocal evidence of that. I'm trying to eliminate other things in the meantime. I noticed these figures here - which I felt weren't all that abnormal - but you never know.
In the last few days, the check engine light started flashing - normally when the car has been left to idle a little while after a 30 minute or so urban drive. It then goes out. I managed to capture the fault code it generated P0301 - a misfire on cylinder 1. I changed the plug from cylinder 1 to cylinder 4 and the same code returned. It doesn't rule out a problem with a HT lead [I couldn't swap those because the others were too short], nor the coil pack obviously. Over the weekend, I took the fuel rail off, cleaned it with compressed air and swapped injector 1 with injector 4... and to my chagrin I'm getting no error codes at all now. Annoying when you're praying for an error code to show [i.e. hopefully having moved with the injector], it doesn't (!)
Looking around online, most of the time the flashing spanner is associated with an injector problem. My injectors sound OK [they all click the same]. I can't test the resistance unfortunately as my meter is caputzio !
