Engine stalling

get a cheap scan tool that reads live data. Check for both the intake air temp and the coolant temp. If either is outta line with expected norms, then more than likely they're bad. Also, check to see if the purge valve is clicking like a mechanical watch. It should increase and decrease with engine speed. These purge valves are notorious for sticking open or closed. It's possible the idle air control valve is bad or sticky, but the pickup would prolly screw up all the time if that were the case, but it never hurts to check it for failure...especially if the throttle body is filthy.

I checked the purge valve and it’s working fine, could it be a bad throttle sensor ? Because the rpm will also drop around 1500 to 1000 when going from a stop, should’ve put that in description as well
