ok, ive just read through this whole thread and lots of very interesting info. thanx to all.
i curently am getting no more than 250km to a full tank, and its been this way for over a year.
im talking 250km max, average 200, 210.
anyway, im convinced after reading this its my 02 sensor. im gonna go pick one up in a n hour or so.
only thing im not usre about is what to do because i have an apexi power fc and not the stock ecu. i heard that the ecu requires resetting but this is not possible with the pfc.
can i just change the sensor and let the pfc take care of it self? as i cant afford to take it to get tuned again.
thanx in advance.
ps: im going for the ngk sensor, if i can find it.
