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

try swapping the afm's around and see if it moves the problem

you got stock cat? maybe drop zorst from cat back and make sure it hasn't collapsed as well

Are you aware that R32's use the cat overheat warning light as the check engine light?

[R.3.2.G.T.R]

brad - engine check light will stay on if any of the sensors aren't working, in your case, AFM

on the powerfc controller, under sensor ckeck, does it highlight the faulty afm as black at all?

Yep it highlights no.2 afm same as the first time on the power fc controller, I've got our auto elec from work is going to have a look at the first set of afm's for me, but as for the warning light that didn't happen the first time the afms played up so not sure if the same issue or not,

Could there be any other cause for the problem like faulty sensor or anything?

This problem has been haunting me for so long i just want to be able to fix it and drive my car somewhat reliably

Spoke to the guys at race pace today he said the cat overheat light is nothing to worry about there shit and they pull the sensors out or dash globes,just means the cat is hot could be some shit in there or faulty sensor but nothing to stress about and also suggested like bwrgtr swapping the afms round and just see what happens so hope to get this shit sorted
