2003 Mustang GT V8 Idle / Stalling issue


Thanks to this forum I have replaced my IAC and my MAF sensor. This has fixed the frequency of my low idle as well as lowered the frquency of stalling. Unfortunately, my car is still stalling when i come to a stop. AC on or off , doesnt matter. I can start my car right up after. I also can start it up or park and ifle for quite a while without stalling or i dont at all.

The alternator was replaced in 2008.
The fuel pump was replaced less than 2 years ago.

I have an O2 code reading because i am missing two catalytic converters. My vehicle is supposed to have 4.

I went to Just breaks and they tried to tell me that my fuel sensor was bad, and they had to drop the tank to fix the idle issue. This was before i fixed the MAF and the IAC.

Of corse I looked into other options.

Can anyone point me in the right direction?

Check your duel pressure, change the fuel filter, and check the alternator.
