Hi,
I have a 94 mustang GT and when I put it in park with the AC off it stalls. Without the AC it is fine...
What can this be? In the old days I would say the idle is too low

I assume you mean it stalls with the AC on. If it idles fine with AC off, check the ac idle up valve and pray it's not a wearing out compressor

Hi,

no it only happens with the AC off. It seems when the AC is on the car idles higher.

Oh and the compressor is new. Matter of fact this only started to happen after it was replaced

Thanks for answering I really enjoy your channel as a 30 yrs television person!
