Problem: Whenever coming to a complete stop or slowing down, the engine stalls out, to start up back again, I will have to wait around 30 seconds and the car will usually start up (this happens RANDOMLY)
my bro is driving this car and said if he adds fuel injector cleaner it will lessen the chance of this happening

Trying to fix the problem: Changed water pump, spark plugs, cam shaft sensor, crank shaft sensor, and fly wheel sensor, cleaned the throttle body and everything still no luck
