Question:
my car stalls as i approach to a stop and when i step on the gas from a stop. starting it again though gives me no problem. idling is fine at 700 rpm,but only after cleaning the throttle body to get rid of the accomulated carbons around the throttle plate (butterfly) .somebody told me i need to replace my idle speed controller. shall i replace it at once or can it be just overhauled or cleaned? does fuel injector has anything to do with this stalling in a way?

Second, unless I'm mistaken, cars around that year don't have anything called a "idle speed controller" in them. The closest thing to this is called the IAC (Idle air control) step motor, and while this cuold be the problem there are too many possibilities for you to just replace it out of nowhere. The best thing to do is take it to a drivability shop and have them do a scan on it to see what all the sensors are doing.

Alternatively, you can replace the IAC or attempt to clean it. There is a very low chance that you will hit the problem spot-on but if you want to gamble the money then its yours to gamble.
First of all, your description tells me that you have a carburetor. If that is the case, your engine does not have fuel injectors.
Carbon buildup on the venturi (butterfly) suggest you got problems with the filters. Are you using aftermarket foam filters? If so, be sure to keep the foam filter cleaned and oiled regularly.

Buy a can of spray carb cleaner, with the engine running at fast idle, spray into the venturi chamber. This should remove the carbon deposits and hopefully other gunk thats surrounding the jets.

If the problem persists, load up on premium high grade fuel and once the engine has properly warmed up drive around in low gear at high speed maintaining 3000+ rpms for at least 30seconds. If you are on a budget, just buy fuel additives and put the entire contents into your tank.
How often should you change the oil in your car?
There should be at least some improvement. If problem still persists, then you probably have a problem with the carb and will need servicing.
