The car stall at low speed or iddling

Chances are you have a vacuum leak or the idle air control valve (IAC) is bad. It is hard for me to understand why trained techs can't work on a car without a scanner. Check for vacuum leaks first (cheapest fix). There are directions on our homepage under the DIY section. As far as the IAC, it needs removed from the throttle body first. There is a pintil valve on it that moves in and out to allow air to enter the engine at low RPM's. When you remove it, have a helper turn the key on and off a couple times while you check to see if the pintil valve moves. If it doesn't, make sure there is power to it. If there is, replace it. If there is no power, then you need to trace wires to see where power is lost. That can become a pain, but would need done.
