Please help me !!!
Been having problems with my 32 gtr stalling and idle rough, spoke to mechanic at race pace and he thought it was an afm problem and showed me how to open sensors and switch menu on the power fc controller and no.2 afm would go to 0.1v and get a big black strike through it showing fault so I purchased second hand afm's to see if it was afm or afm wiring or connection somewhere, changed over afm's car has been good for a couple of weeks no sign of problem since fitting......today stopped on the way home for coffee come back to car won't start well cranks starts then stalls straight away, finally get her going after 5 or 6 trys, and get cat overheat light on dash and power fc controller is showing no.2 afm is not working, well 0.1v instead of 1.69v while driving, I tried wiggling the plug with the car on to see if it will alter idle, which is now rough as guts and it doesn't change, the one thing I noticed with the plug though was when you push no.1 plug on you hear it snap on and lock in place, no.2 doesn't do this its like it's bent up but I pryed the clip to snap shut and lock on and wiggle it still doesn't change. So my question is wtf
Is the 02 sensor or cat the fault? And if so why does it affect only one afm, is it wiring or connection ? Any help is greatly appreciated.
Thanks Brad
