96 caprice cuts of while parking but drives good.engine light is on and the code reads p0443
That trouble code is for the EVAP system purge valve circuit. Check the wiring and plug at the purge valve. If all is good, replace the purge valve. As for the stalling while parking check the power steering fluid pressure switch. When the wheel is turned all the way in either direction a switch is activated to speed up the engine slightly to prevent stalling. HTH. -Jim
