I have an 06 Mustang GT with an AIRAID SynthaMax Cold Air Intake, SVE 3 row all aluminum Radiator, Mishimoto Silicone Radiator Hoses, Ford Performance Fan, new spark plugs & Coil packs.
So my issue is one that I have absolutely no idea what it is as no codes pop up & it doesn't happen all the time.
The issue is that sometimes when I come to a stop, the car sounds like it is misfiring or about to die with the rpms dropping under 500. I can put the car in park & it evens out the rpms & gets...

Rough idle issue and low RPM at stoplights
