I am having an odd issue where my car will actually stall if I am around a loud car at the drag strip or just in general. It had also had an issue in the past where a friends car off a AEM 2 step actually stalled the car out off idle.

To me it seems that the knock sensor is fault causing false knock. The car is a 2003 with 125k miles. The car also has a 15whp spread on the dyno between pulls.

 

That's usally caused by the MAF. Might need to add a little fuel at idle and bump the idle a little more. When's the last time it was tuned?

 

yea mostly like the MAF. My idle drops really low anytime a loud truck/car or even police sirens pass by but it doesnt stall.
