What is wrong with the car if the car stall while I am slowing down and push the clutch in? It is very dangerous because it will stall while driving at about 15km while I was turning and lost my brake and power steering. I was told that it could be a AFM problem but others say it's not. Thanks in advance.

It cud be AFM.
BTW, does ur car hv aftermarket BOV? Aftermarket BOV dumps the boost into the atmosphere. This tricks the AFM into thinking that there's no air coming in because the stock dump valve recirculate the boost into the AFM. Most GTRs with aftermarket BOV therefore tend to stall because of that.
Thirdly, it may well be a mapping problem.

Thanks for your replay R33, my R33 is NA so I don't have the BOV. Maybe is a sign of beginning defective AFM. Is there any steps I can take to diagnose the AFM myself before going to a mechanic? Thanks
