Well to update with current status.
A few days after I last posted, as my clocks rolled over to 80000km, my speedo and odo stopped
working. I followed google and removed the sensor. It had very little grey matter, but I cleaned
it up, replaced it, and also cleaned and reseated the 3 pin connector.
Since that day I have had a working speedo/odo and also never seen an O2 error again....
Then yesterday on my way home, I had a brief engine stumble along with the CEL come on
for about 2-3 seconds and then all returned to normal.
A quick check when I got home showed no error stored and an AFR of 95,6 .
All other tests passed and nothing "seems" out of place.
So my question would be, is this then a sign of a failing fuel pump, or
should I be looking elsewhere. ?
I could run live data on the Buelltooth, but I honestly wouldnt know
what to be looking for.
